Four nuns were standing in line at the gates of heaven. St Peter asks the first,

“Have you 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,” St 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.

Then the fourth nun pushed ahead of the third nun. St Peter asked her,

“Why did you push ahead in line?”

“Because I want to gargle before she sits in it!” she answered.
