Four nuns are standing in line at the gates of heaven. Peter asks the first if she has ever sinned.

"Well, once I looked at a man's penis," she said.

"Put some of this holy water on your eyes and you may enter heaven," Peter told her.

He then asked the second nun if she had ever sinned.

"Well, once I held a man's penis," she replied. "Put your hand in this holy water and you may enter heaven," he said.

Just then the fourth nun pushed ahead of the third nun.

"Why did you push ahead in line?" asked Peter.

"Because I want to gargle before she sits in it!" replied the nun.
