Crossword On The Plane

On the airplane on his way back to Rome, the Pope was doing a crossword puzzle. After a while, he turned to the bishop sitting next to him and said:

- What's a four-letter word ending in ‘unt’ which means ‘woman’?

The bishop said:

- Did you try ‘aunt’?

The Pope said:

- Mmmm. Do you have an eraser?
