A gentleman sits next to a priest on an airplane.
He sees the priest doing a crossword puzzle.
Time passes and the priest 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 priest replies, "Oh, you're right. That fits, too. Would you happen to have an eraser?"
