we all had a dumb moment and have been embarrassed about it

What's the dumbest thing you've ever done in School? Did you get caught by a teacher or was it just in class being embarrassed.
I had a boner in class.
Who didn't?
Well, I fell in front of a bunch of other students, several times.
Same here. Did your fellow students each have one foot out blocking the aisle as I witnessed while picking up my books as they laughed at I still don't know what to this very day?
