A gentleman sits next to a blonde on an airplane. He sees the blonde doing a crossword puzzle.
Time passes and the blonde says, "Excuse me, sir, but do you know a four letter word that describes a woman and ends in 'u-n-t'?"
The gentleman thinks about this and finally says, "I believe the word you're looking for is 'aunt.'"
The blonde replies, "Oh, you're right. That fits, too. Would you happen to have an eraser?"
