Post anything embarrassing that you saw in your class! It can even be you, but it doesn't have to! Go!
A few days ago I brought a laser pointer to school and in class I shone it all around. Then I heard the devastating words: Who has the laser pointer- I froze. But the class turned on me and everyone looked at me and said my name. I got it back at the end of class though.
In 7th grade I was confused because we were grading something and she said she would give extra points of my person's book said something specific. Whole confusion and stuff, I can't exactly remember. But she asked me what 7+3 was, and not being very good at math, I rushed and said 9. The class went hysterical and she was pissed at me.
When I was in 7th grade I asked this girl out. And she said no, and being the hormonical person I was back then, I said stuff like "dang it" "i feel rejected" and other stupid stuff. I didn't even sound serious.
Again, 7th grade. One time I was showing a guy my karate/self defense moves and was using a free-yourself move and he let go unexpectedly and I hit this chick right in the nose. She wasn't in my class and I didn't like her though
