Three nuns decided to quit so they went to the Mother Superior and said, "We don't want to be nuns anymore, how do we quit?" The mother told them, "Do something unholy and come back here in 24 hours." So the nuns left thinking, "What can I do that's unholy?"
The next day they went to the mother one at a time. The mother said tot he first nun, "What unholy thing did you do?" and the nun said "I stole a kid's bike." The mother said, "I guess that will do, go drink some holy water. When the nun did she wasn't a nun anymore and she left the convent.

The second nun walked in and the mother said, "What unholy thing did you do?" The nun replied, "I slept with a married man!" The mother said, "Well, that's sinning. Go drink holy water."

The third nun walked in and the mother said, "What unholy thing did you do?" The third nun said proudly, "I pissed in the holy water!"
