Two Indian doctors were having an animated discussion. “I say it’s spelt W-H-O-O-M,” said one. “No, it’s W-H-O-M-B,” said the other. A nurse passing by said “Excuse me, you are both wrong. It is spelt W-O-M-B.”

“Thanks nurse,” said one, “but we prefer to settle this argument ourselves, besides, we don’t think you are in a position to describe the sound of an elephant passing wind under water.”
