Four nuns were at the Pearly Gates, asking St. Peter to pass. St. Peter asked them each a question: "Have you ever touched a penis?" The first nun said that she once did, with her finger. St. Peter told her to wash her finger in the holy water and enter. The second nun said that she once did, using her hand. St. Peter told her to wash her hand in the holy water and enter.

The third was about to speak when the fourth nun jumped up and said, "Let me wash my mouth, with the holy water, before she has to wash her butt!"
