Wash with holy water for entry to Heaven.

Four nuns were 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. “Use this eye dropper with holy water in it and you may enter heaven,” Peter told her. Peter 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. Peter asked her, “Why did you push ahead in line?”  She said, “Because I want to gargle before she sits in it!”
