There is a priest and three nuns.

The priest tells the nun, you have all served your order well. You can all go out into the world and do what ever you want to do tonight.

But you have to come back tomorrow morning and confess your sins. They all agreed and went there ways. The next morning at confession the first nun walks in and says forgive me father for I have sinned. What is your sin my child? I slept with a man. Ok go say 3 hail marries and drink the holly water. The next nun comes into confession, forgive me father for I have sinned.

What is your sin my child? I slept with a man and a woman. Ok go say 10 hail marries and drink the holly water.

Then the last nun walked in and says, forgive me father for I have sinned. What is your sin my child? I peed in the holly water.
