well alot of my teachers do funny shit but it usually isnt written on the board.
in 7th grade, my english teacher taped a blank piece of paper on the board with an arrow to it saying "dont look." of course everyone looked and there was nothing under it.
my global teacher always has random shit written on the board that students do. one say some annoying chick wrote mr trombley is a meanny. so he goes and writes ali smaok is a keebler elf.
then my spanish teacher said something to me that was pretty funny. i was kinda sick so my voice was a little deeper than ususal and i answered a question and she asks "are you sick or are you just finally hitting puberty?"
then my english class is just amazing. 2 days ago we walk in and my teacher is like ok take out a piece of paper, its time for out mid-term! everyone was like whattt you never told us about this. then hes sitting at his chair playing with a coke bottle and hes like "im not holding this just because i drank it, its becasue if anyone shouts out an answer, i will throw this at your head. ok question 1, a farmer has 17 sheep, all but 9 die. how many are left?" some kid shouts out 9 and needless to say he got a coke bottle square in the forehead. "ok next question. why cant a man living in Missouri be burried west of the missisippi? the rest of the questions were dumb ones like that, and 6 kids got hit in hte head with a coke bottle.
