What is the most embarrassing thing that has happened to you during a school event?

I was wondering what is the most embarrassing thing that has happened to you during school or a school event. Well here's the most embarrassing thing that happened to me. For raising money fro charity we got to have a fun day and we got to dunk the teachers ina dunk tank. Well I was probably standing to close and i was wearing a white and black shirt and skirt and when the teacher fell in I got splashed and through my clothes you could see my black bra. I had to run inside and put my gym sports bra and gym shirt and shorts it was so embarrassing but worst things have happened to my friends. FIrst when we were younger their was a school lock-in event and one of my friends who was a boy was there and so after 10:00 pm the adults locked the door out so kids would sleep and not wander the school. So anyways my friend really had to go to the bathroom but couldn't so he tried to hold it in but couldn't and eventually fell asleep. Then at the morning he woke up and his pants and sleeping bag were all wet but he got up earlier then everyone so he took a water bottle out of his backpack drank it and tipped it over so it looked like it had spilled on him so no one ever knew until he told me. This is the embarrassing thing I'm most sad so my boyfriend hes blind and when we went to this athletic place with a pool for a field trip I convinced him to go swimming but when he walked into the changing room to change he accidentally walked into the girl's changing room and all the girls screamed and freaked until I told them he was blind. Most of the girl's were fine with it but my boyfriend felt really bad so for like the next month he was obeying the girl's orders left and right but he eventually got over it. So does anyone else have embarrassing stories like this?
