Replying to How to get back at the football coach?

alright so i play soccer and the football teams coach is seriously such an asshole. the football team is cool, but their coach is a total dickhead. the other day we go up there and are supposed to practice and he calls as "grassfags" and tells us to go practice somewhere else. our coach wasn't there so i decided to yell back "come over here and say that old man". he came over and is probably 5'7" 250 lbs of fat. so anyways to make a long story short he tried to get some players on his team fight me (all freshman and seriously like 12). anyways i need to think of the best things to do to fuck him over and not the actual football team (since they hate him as well). i know NS has some good ideas on this shit so lemme hear em!
