What have your classes done to a teacher?

[Bad Hamster]

My class, one lesson, wrote on the interactive whiteboard that our teacher was a virgin, while he was teaching the class, and his real name is Fergilicious (his name is Fergus). When he went to go and get senior management, he got locked out the classroom for the rest of the period.

What have your classes done to teachers?

I think this is childish. That's just me though.
We don't really do things to teachers, we more talk and have fun.
They say themself ' It's your choice to make it, not our'. Basicly they don't care if we fail, so we can do what we want. Worst thing we probably done was coming 40mins late for class.
