with your fists in front of all his buddies. It did the trick when I was in high school.

I used to get suspended regularly, then again it wasn't just me but half the class, smoking in bathrooms, vandalising bathrooms, desks, windows, doors, defacing walls, electrocuting little ones, intentionally marring recital of national anthem at assembly, throwing leftover lunch into ceiling fans, dismantling light fixtures, switches, plugs, removing fuses, cutting class, fleeing school to wander around town, knifing the staff's tires, playing dodgeball with balls meant for cricket... it's amazing I learned anything, but I did learn the value of good comradeship, through thick and thin :D
