Four Nuns At Heaven's Gate
Hope I don't cross the good taste line here, but I have to tell this one.
Four nuns are waiting to get into heaven and God asks the first one, "Have you committed any sins?" She says "Yes, I once touched a man's penis with my finger." God says "Put your finger in holy water and you can get into heaven." He asks the second nun the same question and she says "I once gave a man a handjob." God says "Wash your hand in holy water and you can get into heaven." The fourth nun then goes ahead of the third nun and says "If I have to wash my mouth out with that water, can I do it before she sits in it?"
