There where three nuns who never did anything wrong. One day the high priest came to them and told them that in order to become better nuns they had to do something bad and then drink from the holy water. So the three nuns went out that same day and did something wrong.
The first nun came and the high priest asked her what she did wrong. " I took a lollipop from a little kid." So he let her drink from the holy water.
Then the second one came back and the high priest asked her what she did wrong, she said " I took a balloon from a little kid." So he let her drink from the holy water.
Then came the third. "What did you do wrong?" asked the high priest. " Well", she said," I peed in the holy water."
