A coach full of nuns go over a cliff and they all die. They find themselves in a queue outside the Pearly Gates. St Peter suddenly appears and approaches the nun at the head of the queue and says "Sister before I can let you into Heaven you have to answer one question. Have you ever touched a mans penis?"

The nun blushes and admits to having once touched the end of a man's penis with the tip of her finger.

St Peter smiles and tells the nun to dip the offending finger into a nearby font of holy water and pass on into Heaven.

St Peter then turns to the next nun in the queue and asks the same question. "Sister before I can allow you into Heaven you must answer one question, have you ever touched a man's penis?"

The nun blushes and admits to having once held a man's penis in the palm of her hand.

St Peter smiles and tells the nun to dip the offending hand into the nearby font of holy water and to pass on into Heaven.

At that moment there is a commotion at the back of the queue and a nun is seen sprinting from the back of the queue all the way to the front. St Peter looks perplexed and asks the nun what in heaven's name was she up to?

The nun looks at St Peter guiltily and replies " If I've got to gargle with that holy water I want to do it before Sister Mary has to dip her arse in it."
