Most embarrassing junior tech moment? Go!

On my internship, I broke an £800 low impedance high bandwidth scope probe by pressing too hard and snapping the (apparently non-serviceable) tip. :-BROKE

Oh, yea, I once did a board layout where I reversed power and ground on just half of it.
Njk:
Designed a new board version, that uses a cable for power and signals. For better PCB layout, changed power and ground pins in the cable connector. Sent the engineering note to the factory in China, requesting to manually swap the PWR and GND pins in the existing cable stock. But the factory guys are very smart and well trained. They quickly realized that the pins in the cable connector needs to be swapped. On reception of my note, they swapped the pins one more time, resulting in the original configuration...

Dataplex, around 1995 - I installed a (very expensive) 540MB 2.5" hard drive in a prototype controller for a SNMP-managed bank of modems. A chip on the bottom of the drive exploded, a piece flying across the room. Of course it was NOT the engineer's fault for using a non-keyed drive connector, it was mine for not knowing that he had and which way was it was supposed to go!

mistaking the fire alarm circuit for a socket circuit,meter out to confirm its dead and bells started ringing,one office evacuation and 2 fire engines later i found the correct cable.
