Ah yes. That moment when you would give just about anything to have your product fail in a nice predictable manner.

I have a reputation for fixing intermittents; fly me over and back and I will fix it.

Few things i normally try,

Hit it, repeatably,
Get out a hair-drier and heat up the box to something quite uncomfortable
Add some ground, or supply resistance for its power supply
Load down its outputs
provide a pull up or pull down on inputs or outputs
walk away yelling,
quickly race back and catch the thing off guard
pick up, violently shake object and event bang on bench
Call working, bill for time.

I usually give my broken electronics some encouraging words... it's worked a few times!  :-+

My favourite are the bugs exposed by human factors.  You have some process that works just fine, but then some new operator comes along and things start failing intermittently.   It's a lesson in humility to sit there watching what they do to expose a bug you created because you couldn't conceive of them doing it "that way" and what the consequences were.
** Bonus humility for creating some standard operating procedures which you think will prevent the bug, but then learn it's still present.   Extra bonus humility for blaming the operator (even if only in your mind) for not following the SOPs when in fact they did. **

Electronics and mechanics are easy.  Just regularly approach them with a screwdriver.  Let them know you are not afraid of taking them apart! :)

Reminds me of the 'Antennagate' 'You're holding it wrong' fiasco...  ;D

That's exactly it Mr. Crispy.  If they had only included a little piece of paper that said "For your proper Apple(C) IPhone(C) experience(C), hold your phone like this:" then you could conceivably blame the user.  You would know in your heart it was really your fault for not providing a robust design, but you can use a SOP to weasel your way out of it.

Fluorescent lamps are also useful in such cases, mainly as a noise source at 50 and 100Hz .
I am available for freelance work.

I forgot to put it somewhere cold last night, so it's been fine whenever I've tested it today. It's now in a cold room, so will see what it does in the morning.
