What's your most embarrassing memory?

I can't really decide which one is my most embarrassing one, so I'll just give you one of my tops. :D I was in school and I had to use the computer room, during the break time. I was in a rush, so when I saw the classroom I didn't bother to wait or even think before I quickly opened the door and burst into the classroom. As soon as I walked in I noticed that it was very quiet there and that everyone was looking at me in a really strange way. Assuming that it was probably nothing, I started walking towards the nearest chair and I almost sat down, right before I was stopped sa pamamagitan ng a really angry teacher, who whispered at me angrily and kicked me out of the classroom, while other people in the classroom (along with me :D) tried really hard not to laugh. It turns out that I, with my very smug and rushing attitude, pretty much ran into an ICT EXAM! :D Even though it WAS pretty funny, it was also really embarrassing :P
