Nuns at Pearly Gates (18)

Three Nuns die in a car crash and go to see St Peter at the Pearly Gates.

St Peter says, "Before you may enter heaven, you must confess any sins."

Sister Mary steps forward and says, "Forgive me, but I once saw a man's penis."

"Very well. You must now wash your eyes in this bowl of holy water, and you can then enter," explained St Peter.

All of a sudden Sister Ann pushes past Sister Jane, to get to the front. "What's going on here?" bellows St Peter.

Sister Ann replies, "I want to wash me gob out before she sticks her arse in it!"
