Horrible Exam Stories?

It didn't happen THIS year but... The night before my microbiology final I couldn't sleep well. I finally looked at the clock and through my strained eyes I thought it said 5:00 am so I thought what the h*ll. I got up, showered, got ready to go and looked at the clock again and it was 2:30 am. By then the shower had made me sleepy and I laid back down and fell asleep. I must have turned my alarm off in my sleep and slept right through my 8:00 am exam. Luckily, my professor liked me and knew I was a serious student so he let me sit down and take it right there in his office.
