Uhm, just a couple middle fingers >> but dude, the ones that I've done it to totally deserve it D: My last geometry teacher was a [insert female dog]. She never let us ask questions, and when ever we did she would basically ask us the question we just asked her without giving an answer...she pretty much called the class stupid a few times...NO ONE liked her at that school, I mean, go up to anyone who knew her and they'd say something negative about her... lol I'd joke sometimes about how down that hallway, it was always hot and that it was because her room was Hell xD I don't really remember the other mean teacher I did it to, but I'm sure they deserved it, it takes a lot for me to that mad at someone ]:
