The Pope
A shy gentleman was preparing to board a plane when he heard that the Pope was on the same flight. "This is exciting," thought the gentleman. "I've always been a big fan of the Pope. Perhaps Ill be able to see him in person."
Imagine his surprise when the Pope sat down in the seat next to him for the flight. Still, the gentleman was too shy to speak to the Pontiff. Shortly after take-off, the Pope began a crossword puzzle. "This is fantastic," thought the gentleman. "I'm really good at crosswords. Perhaps, if the Pope gets stuck, he ll ask me for assistance."
Almost immediately, the Pope turned to the gentleman and said, "Excuse me, but do you know a four letter word referring to a woman that ends with the letters 'u-n-t?'"
Only one word leapt to mind...
"My goodness," thought the gentleman, "I can't tell the Pope that. There must be another word."
The gentleman thought for quite a while, then it hit him. Turning to the pope, the gentleman said, "I think the word you're looking for is 'aunt'."
"Of course," said the Pope. "Do you have an eraser?"
