One afternoon, two doctors from India were having an animated discussion. "I say it's spelled 'W-H-O-O-M'," said the first Indian doctor.

"No, no, no, it is 'W-H-O-M-B'," said the other Indian doctor.

An American nurse passing by said, "Excuse me, you are both wrong. It is spelled 'W-O-M-B'."

"Thank you nurse," said one of the doctors, "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."
