Man, that brings back memories. In high school we used to get stoned and then play D&D for hours (sorry guys no demons every showed up and no I never started worshiping the devil - we were all about scoring with virgins, not sacrificing them [what a waste of a virgin]).
Coolest character was this half dark-elf/half-human wererat assasin. I also had a pretty solid druid, although he was SOOOOOOO hard to work up. Good times, good times . . .
d00d, the guys in my highschool who played D&D not only never smoked pot, but got their @$$es kicked daily by the people who did.
