The Pope was working on a crossword puzzle.

He thought and thought about one clue, finally gave up and asked the Cardinal next to him, "What's a four letter word, ending in U - N - T that means 'woman?'"

The Cardinal was working on his own puzzle and didn't even bother to look up. "Aunt, your Holiness."

The Pope didn't speak for a second, "Oh. Do you have an eraser?"
