I had one in high school in Trigonometry that came up with some funny ones. Here's one:"Rudoph is up on the roof of a house waiting for Santa to huury up and deliver the presents. Down below in the bushes 30 feet away there is a deranged hunter with a rifle. The roof is 40 feet high, and the hunter's angle of trajectory is 30 degees. Will Rudolph be killed?"
