Trapped in an elevator. Pry open the doors. Odds are you can climb up or down to the next floor. Failing that, use the emergency hatch at the top and climb up to the last floor. Of course, if you can't do either... you are pretty much hosed.

Locked naked out of my room. So not gonna happen. Momma didn't raise no fool, I don't leave the room unless decently clothed.
