The pope and one of his aides were traveling across the Atlantic on plane, and during the flight, the Pope tried to catch up with one of his crossword puzzles.

Midway through the flight, the Pope leans over to his aid and whispers: "what's a 4-letter word that means 'woman' that ends in unt?"

His aide thinks for awhile and triumphantly says, "I have it. it's Aunt."

"Oh dear", says the pope, "do you have an eraser?"
