When I lived in SD, we played paintball up in the hills and one of my roommates crawled right through poison ivy. I was going to tell him (didn't figure there was that much of a hurry because we were in full fatigues so I wasn't all that worried about him rubbing his arms or anything), but we were in the assault mode on the flag (all got wiped out by the way, pansy ass flag sitters.....

) anyway I didn't get a chance to tell him until later and he had already went behind a tree and relieved himself. I kind of felt bad, but it was kind of funny.
