John walks down one side of the street. He wears camouflage trousers. A friend walks up the other side of the street. They wave at one another and continue. The friend stops suddenly.
Friend: JOHN! WHERE ARE YOUR LEGS?
John looks around confused. He looks down at his camouflaged trousers.
Friend: Oh, you are wearing camouflaged trousers! Oh, thank goodness! I thought you lost your legs!
