A priest is on duty in the confessional and desperately needs to take a piss. He looks around and finds a young nun and asks her to sit in for him.

Nun: "Is there anything I need to know?"

Priest: "Just listen to whatever their sins are, look it up on this list and give them the penance listed. It's easy! "

So the nun takes over, and it's going according to plan. Ten Hail Mary's here, a Rosary there...

After a while, a girl enters the confessional and says that she has given her boyfriends 5 blowjobs since her last confession. "Blowjob" is not on the sin list, so the nun opens the door to see if anyone is around. She is happy to find an alter boy and asks "What does Father Phil give for blowjobs!?!?!"

"Usually a Snickers bar... but he give me a soda also to wash down the taste!" said the alter boy proudly.
