My worst was in 1996. I had been sent to Dubai for three weeks to work on a new system. It turns out our programming team (just 2 of us really) were actually part of a much bigger system that had about 10 teams, and a total of about 300 programmers.
Anyway, I ended up being there 3 months and we were pulling in about 90+ hour weeks. In one month I did 156 hours overtime. A normal day was starting about 7am and finishing about 12pm.
In the end the whole lot went live on the same day. It's all to do with travel systems so it was quite cool to see information appearing from across the globe as areas woke up. Anyway, the main company (Emirates airlines) decided, probably very stupidely, to have a big party that same night.
We went to that big hotel that looks like a boat, or sail, whatever. So there we were about 300 programmers all dressed in these red T-Shirts with the system logo and everything (Mars). And we drinking away merrily mingling with the other programmers and watching a speech by the head of the airline (some sultan or other) thanking us etc. No worries.
Then about 1am all the European teams went to the outside terraces and sat down by the sea to get blotto on various spirits. Suddenly all mobile phones went off. It was like siren city or something. Turned out pretty much every system was erroring and the whole thing went down. All the Indian teams (about 250 or so) zoomed off. All the Europeans stayed where we were. Too drunk to really care and probably would have caused damage anyway.
Next day we spend something like 12 hours debugging the system. Then we watched it (the client insisted) for another 24 hours. We brought in playing cards, games, booze, the lot, but the client stayed until about 4am, so we had to wait to get them out. Annoying.
I was so tired that I fell asleep in a meeting the next day and got sent home. Interesting colours and light headyness on the way back.
Great times though!
Cheers
I am 99% probably lying in bed right now... so don't blame me for crappy typing
