Wow, this weekend has been very violent... I think I'll join in...

Stab him in the scrotum with a toothpick! Friggin, take him to the middle of howhere, make him get nekkid, then spread caustic paste all over him and leave! That'll learn 'em!

OK...the drugs are kicking in now...

Seriouslly, be a man, take a stand, and say what you gotta say. If it has to get physical for him to understand, then it has to get physical. But don't get punked down b/c that gets around and other people will punk you. You don't have to make a big scene about it, but don't be a pushover either.
