A nun gets on a bus thats empty except for the driver.
She says "I'm going to die soon but I want to have sex before I die. Problem is I must remain a virgin so it has to be to ass. I can't commit adultery, so the man must be single.Can you fulfill my wish?"
"Yes" says the bus driver and fulfills her wish.
Feeling guilty he says "I'm sorry I lied, I'm married with 3 kids."
"Thats ok" replied the nun "I lied too."
"My name is Kevin and Im going to a fancy dress party."
