More recently, whenever someone leaves their computer unlocked and leaves their desk, we would bring up https://fakeupdate.net/win8/ in a web browser set to full screen...

That is just gold.
I am going to use that this week...
Love that pressing enter emulates a BSoD.

That image of the cracked LCD screen and set their screensaver to it.

Talking about cars. A colleague bought a new Ford Escort RS2000 and would not stop banging on about it. So one day we poured a cup of engine oil on to the tarmac underneath making a nice puddle and a trail out from under the engine bay. We made sure we all left work at the same time just to watch the priceless expression on his face...

Three in a row, in 30 minutes.

Victim: my sister

Her tire was flat and I offered to change it. While I was jacking it up I suggested her to go to a garage
to have the wheel checked just in case I did something wrong. As I don't have a driver's license I told her
I am not licensed to replace tyres, so she would be in trouble if the wheel somewhat failed. (strike 1)

While lowering the car I recommended her to move away from the firing range just in case a bolt was shot
at high speed due to the weight of the car. (strike 2).

After finishing the job, while heading back home, I told her I remembered that she should try and start the engine.
As she was aware I had pulled two pranks already she was wary. So I explained there is an effect called "engine vertigo"
that might happen when the car has been tilted for several minutes. There she went and started the engine that, obviously,
worked (strike 3).

The funny thing is, she fell for them three times in a row. And being my sister you can imagine she knows me very very well  :-DD :-DD :-DD :-DD

Another one, this one was 35 years ago! I was the lighting and sound technician for a theatre company. We had an opening on Sunday and I
told the director I was going mountaineering on Saturday. On Sunday some of the crew went to a radio station to be interviewed about
the opening and meanwhile, to the astonishment of the radio guys, I was bandaging my hands. So, I appeared at the theatre with both
hands bandaged. I told him I had an accident, it wasn't serious but my hands were out of order. So, he had to sit at the lighting and sound
control waiting for my instructions.

The play begun and I poked him in the shoulder, and I showed him how I was removing the bandages. He almost killed me, although at the
same time he felt an immense relief! The funniest thing is, several months ago he overheard me telling an actress that I was intending to
pull that prank the opening day. But he forgot!  :-DD :-DD

Pot their car keys in clear silicone gel . . .  >:D

If you've ever had to rework a module potted in the stuff, you'll know just how obnoxious it is to remove.

I almost forgot about this one from a summer job in high school.  It was a small operation, just three of us, myself and another student plus the employer who had two computer systems.  One was for production work and didn't run Windows and the other was for administrative stuff and was a brand new Windows 98 machine.  I added this to his autoexec.bat file:

Code: [Select]
@echo Hi Ray!
It didn't get noticed and I thought it was a bust of a prank.  Months later, long after I forgot about this, I got this angry shouting phone call about how [Other Employee] was sabotaging his computer.  On and on about how the other guy was sabotaging his computer and finally after asking what had been done to it, he told me the computer had been changed to say, "Hi Ray!" on the screen whenever he started it up.  I had to choke back laughter on that and told him that if that's all that had been done, the computer was still in fine shape and not to worry about it.  I found out from a couple of other friends though that they'd also gotten these angry venting calls about the computer being sabotaged and apparently he called the other employee who'd by then quit and only got further enraged when the other guy denied everything.  It was priceless.

Nali and MadHippy: Great minds think alike: many years ago I had a chum who was a mathematical genius but when it came to practical matters we decided that he had 'ExoVision' and could not visualise what was inside anything solid. His pride and joy was a BSA B33. One day I was walking past his house with another friend. We had visited the local hostelry and were transiting to the next pub. The bike was sitting on the driveway, so I asked my friend if he had some old engine oil. We staggered off to his house to fetch a gallon can of it, and proceeded to lean the bike over and pour about half of it into the joint of the head and barrel fins. It cascaded down like a black champagne fountain. Shambling off tittering we promptly forgot about it until a few days later I passed by and saw my chum amid a heap of tools and the head off the bike. "Bloody head gasket has gone..." he whined. My friend and I swore on our lives never to tell anyone what we had done. Not sure how he imagined 2 litres of oil could come out of the head gasket...

Never use the toilets at a Chemistry Block at a Uni, one prank was to paint all the toilet seats with dilute silver nitrate.
Not easy, not hard, just need to be incentivised.

Best prank I helped pull on a co-worker was when he brought his old (antique-ish) phone from home to put on his desk. One with a dial instead of push-buttons. He declared it no longer worked. Working at a telefom related company we had a whole bunch of parts that would fit in it so one day when he was away we fixed the phone and connected it to a telephone line. When he was back we rang him. He was flabbergasted when it started ringing and even more surprised there was someone at the other end of the line.

It's a Ford FFS, oil leaks are part of the design !
I should know, I've had a few of the things !

Several decades back when twisting spanners on small motors and mostly before the days of them new fangled CDI's and such ignitions we would charge points ignition caps with ignition cap testers and lob them at 'mates' for them to catch.
You got wise to it pretty quick.  :phew:

Now most cars have air cons its common to see a trail of drips on the ground that leave you thinking "is that condensate from the air con, or is my coolant system leaking?".

Not completely on topic, but I was reminded of an unusual event...

I knew a component manufacturer's rep, who bought himself a big, fancy Cadillac to impress his customers and carry them to all those "free lunch" meetings at the local restaurants.  Free food is good!

However, there was something wrong with this new car.  Every once in a while, you would hear a "clunk" sound emanating from the car.  This sporadic sound usually happened while the driver was making a sharp turn.

The rep took his car to the dealer, but they couldn't find anything wrong with it.  He drove it around for a few more weeks, but the occasional noise persisted.  So, the rep returned to the dealer for a second look at the problem.  Fortunately, on this second visit, he got a sharp technician who managed to find the problem.

The technician noted that the annoying "clunk" sound was coming from the vicinity of the passenger-side, rear door.  The tech detached the interior door panel.  Inside the door, he discovered a screwdriver dangling on a length of twine.  A note attached to the screwdriver read, "I Hope This Drove You Crazy, You Rich Son-of-a-B**ch".

Some anonymous assembler, at the Detroit factory, just wasn't a happy camper.

We played a prank on a conspiracy-theorist electronic engineer from Bulgaria. He was a little aggressive, so you knew your limits.

On one occasion a good colleague of mine named Greg (who sat in the next cubicle to the Bulgarian) was chopping wood on a Saturday when a chunk of timber hit him in the face, causing a severe black eye, cuts and heavy bruising to the nose. We were good friends out of hours and he visited me on the Sunday. We hatched an evil plan to fool the Bulgarian. Greg would come to work a half hour late on the Monday morning. So before Greg arrived on the Monday, when the Bulgarian asked where Greg was, I told him he might not come to work today because I had bashed his head in on the weekend by delivering several hard punches to his face in response to Greg saying a rude word. The Bulgarian was a little perplexed, but continued to work. When Greg finally rocked up to work bruised and bandaged, he sat down at his cubicle. The Bulgarian looked over the top of the partition, saw him, and then quietly sat back down without saying a word. For about 10 minutes the Bulgarian was frozen - hands on keyboard not moving a muscle, staring at nothing in particular on the screen, not saying a word. Gotcha! After 10 minutes, he looked over asking Greg why I had bashed him. We then told him the truth. The Bulgarian took it OK and was relieved that I was not a nutter (or so he thought).

But you have to be careful of pranks and stunts in the workplace. At one large corporation, there was a forklift driver who was showing off doing donuts in his forklift. The edge of the forklift hit a bystanders foot, taking a large chunk of the flesh from his heel. Not good. The incident was covered up.

In Bulgaria we have a saying:"Бии за да те уважават".Translates roughly to Fight(as in being physically aggressive ) to be respected.So you got some respect points  :-DD

A colleague of mine was powering on a new development kit worth some thousands of pounds and was not sure whether he had the polarity right as the AC adapter was missing.  I scrunched up some tin foil behind him and made a pop sound, and he panicked and grabbed the off button.

At my first intern company, we pranked our operating manager with a "high tech" Ding Dong Ditch. It was a small company with an open office space, a meeting room, and 2 separate offices for the technical and a commercial/operating manager. The operating manager was most concerned with receiving customers and certain letters (trolls/scammers sending registered mail with fake bills to small companies), so he wanted to keep a close watch on the mail and front door to handle that. Of course, his office was farthest away from the door, so that didn't really help.. further worsened by a malfunctioning door bell of the old office place..

It broke a few weeks before I started my internship, so my first task was to fix it. Being an old rental place, the electrical panels was a mess with 0 documentation. So eventually we gave in and bought a battery-powered wireless doorbell that could be attached with some sticky tape on the door frame and inside. Great; door bell fixed. Let's get back to work.

Then one day, both managers were out of office for an external meeting, so we tossed the idea: what protocol is that door bell using? It's probably some 433MHz OOK radio, and since we had several IoT boards that also used 433MHz radio's.. well, how hard can it be? Some quick spectrum analyzer and oscilloscope sweeps later revealed the "magic code" that was transmitted by the button unit to the alarm unit in order to ring the bell. Great: let's hard-code the magic code into a PIC microcontroller, and of we go. :-/O

So come next day.. everyone is back into the office again. A colleague had this board on his table, and it would send the magic code every time he would connect power to the board. Of course, the COO was keen on handling door matters, so checked a couple times when the "bell" rang... no one there.  Becoming more confused every time, he eventually took off the button unit and removed the battery, and the door bell would still rang (of course). At this point it was very hard to hold the laughter, so we gave into the prank. :-DD

Being a small company tight on finances, the first question he asked was: how much engineering hours did this cost us?! :scared:

Co-worker would pretend to let the air out of my tires.  The lunch/break room had nice big windows where you could see out to the parking lot and it was a small company so you could easily see your cars.   While we were at lunch one day he walked beside mine and kneeled down and took off the valve cap and pretended like he was letting air out.
So a couple days later when he was back at his desk I walked over while twirling a ratchet, sat a big bolt on his desk and walked away.   Come lunch time we watched as he went out to his car and looked everywhere trying to figure out where the bolt had come from.

Reminded me of a phone prank on the Bulgarian. He was a FPGA programmer when we were developing a PABX phone system. Our office of about 70 people used the same system for user testing which was also connected to the public telephone network, but our development machines were electrically disconnected from the office and the PSTN. Effectively they were stand alone PABXs with a few feature phones attached - once for each engineer's desk typically. One day another engineer switched the RJ11 cable that was connected to the Bulgarian's office phone into the back of one of the phones on his development system. The engineer called the phone extension from his desk. The "isolated" phone rang once. The Bulgarian looked at the phone, thinking there was a bug in his development PABX as around that time he had some issues with his XILINX FPGA. A minute later, it rang it again. Same thing. The Bulgarian started checking a few lines with an oscilloscope. A minute later, it rang again several times. He picked up the phone and said in a quiet voice "Hello?" :-DD. I remember the engineer sitting next to me broke down in hysterical laughter, so much so that tears were running down his face. I have known that engineer for many years and had never seen him crack up like that in uncontrollable laughter.

There's a well-documented story of this happening on a Ford product, might have been a Lincoln.  There was a large nut on a string in a door.  it was found by the dealer, and sent up to Ford management with the VIN number.  It was supposed to have been QUITE a moment when the line manager walked up to the guy who assembled the door that day (they had extremely detailed records of who did what when) and asked him if he had lost anything recently.

Back when TVs still used CRTs, a common prank was to swap the wires of the horizontal deflection coils. One would get a mirror image on the screen.

Another in color TVs, was to interchange the RGB signals.

At one of the first companies where I worked (I don't remember which one), an engineer had designed a rack of equipment and was preparing to power it up for the first time.  Undetected by the engineer, a technician had positioned himself behind the tall rack.   Just as the engineer threw the power switch, the technician started blowing cigarette smoke through the back of one of the card cages.  I was standing off to the side and the panic-inducing effect was pretty convincing!

======

I remember another prank, where I was the instigator....

Back in the early 80's, my company had a dedicated Perkin Elmer minicomputer that was used to write circuit board testing programs, for complex logic boards.  This minicomputer was set up to timeshare four user workstations.  These four workstations were located side-by side, in a common area.  The computer was fast for its time, but the actual third-party application software ran noticeably S-L-O-W.

The minicomputer and its administration terminal were located in an unsecured room, with the operating system manuals stored in a bookcase.  Reading the manuals, I found the specific OS commands to change how the user time slices were divided up.  The existing allocation was 25% to each of the four users.  The next morning, I changed the time slice settings, so that I got 97% utilization and the other three users only received 1% each.

Returning to the workstation area, my three coworkers had quickly detected that something strange was going on.  They began complaining among themselves that the system, which had always been slow, was now almost useless.  Meanwhile, I was happily working away, with my programs moving along at a lightening pace.  My computer bliss didn't evade detection for very long, however, as the others soon noticed that I was the only person in the room who was NOT complaining! :)

You were too greedy.  17%:17%:17%:49% would have ~ doubled 'your' workstation's speed, and would probably have gone unnoticed for a long time, (or at least till someone else had cause to use 'your' workstation).
