Once upon a time as a developer for Palm handhelds I wrote an application in C which had to print via a Bluetooth printer.
When connected by wire everything was perfect, switching to BT it kept crashing for weeks without me finding the source of the problem.
Then came the day of my companies summer party. I've been the last guy to sit in front of the PC, investigating my problem, when at about 9 PM my boss came and told me, I should grab something to eat. So I went down, drank three beer and got back to work.
At about 9:45 PM the damn wrong * was replaced by the correct & and everything was fine.
