For my senior year at DePaul, my best friend and I lived in a top (fourth) floor apartment on Lawrence. Our back deck/fire escape had a trap door in the ceiling where you could boost up to the roof and admire the view. We had a big party in October and one of our friends got obliterated. He decides to climb up there and manages not to fall off, but comes down pretty hard when getting back down to the deck. He rides his bike home (over a mile) and passes out in his apartment. He wakes up the next morning with his ankle swollen to the size of a grapefruit. He managed to break his ankle when he landed, then rode home on it. At least we didn't ignore him (and he can still walk)
