Let me start by saying that, in general, I don't frequently wish bodily harm on people. There are some exceptions, though, more frequently, those exceptions fall into the category of "I wouldn't care if something bad happened to person 'X'."
Today, I was watching the NFL playoffs. At one point, a player ran into a pile-up of players and his helmet came rolling out of the pile. Sometimes, when such things happen, I wish the heads were still in them.
