4 Nuns die in a car crash and are met by St Peter at the Pearly Gates.
St Peter welcomes them, and tells them he must ask a question before allowing them access.
He turns to the 1st Nun and says:
"Sister, have you ever touched a mans penis?"
The Nun looks flustered, and finally admits that she did touch one once with her finger.
St Peter points to a font and tells her to wash her finger in the Holy Water before entering heaven, then turns and asks the same question to the 2nd Nun.
The Nun admits to having touched a mans penis with her whole hand, and is told to wash her hand in the holy water before entering.
All of a sudden the 4th Nun pushes the 3rd Nun out of the way and barges upto St Peter..
"Whats the meaning of this?" demands Peter...
"Well", replies the Nun..."If im gonna gargle in that thing, i want to get there before she washes her arse in it!"
