One night, a cabby picked up a nun. While he was driving, the cabby suddenly started to laugh insanely.
"Why are you laughing?" Asked the nun.
"Oh, It's nothing." said the cabby.
"No, really." said the nun "I won't mind."
So the Cabby told her:
"Well, It's really silly but I've always had this fantasy of having a blow job done by a nun."
"Well then, whats your name?" The nun asked
"Robert"
"Are you married?"
"No."
"Are you christian?"
"Yes."
"Then Pull into the next alley."
The cabby was stunned. but he didn't want to give up this chance so he pulled into the next alley. When they were finished, they returned to the cab.
While driving, the cabby started to cry.
"Why are you crying?" asked the nun
"I'm sorry, I've lied."
"How so?"
"Well, My name is David, I have a wife and three children, and I'm Jewish."
"Well, I've done a bit of lying too..." smiled the nun "My name is George and I'm going to a costume party."
