Funniest Exam Stories

I did my GCSEs earlier this year and half way through my last exam one of the invigilators (this was the most bossy one) sat on one of the desks at the back of the hall and it collapsed under her and mad a huge BANG right in the middle of this exam, and we all turned around to see this invigilator lying on the floor apologising for the noise and disruption, but it was so funny, it's so hard not to burst out laughing!

So I was wondering if anyone else had any funny stories of crazy things that happened in any of your exams??? :smile:
