A nun gets into a cab and the cab driver wont stop staring at her.

She asks him why is he staring and he replies,
I have a question to ask you, but I dont want to offend you.

She answers, My dear son, you cannot offend me. When youre as old as I am and have been a nun as long as I have, you get a chance to see and hear just about everything. Im sure that theres nothing you could say or ask that I would find offensive.

Well, the cab driver says, Ive always had a fantasy that a nun performs oral sex on me.

She responds, Well, lets see what we can do about that. First, you have to be single, and secondly, you must be Catholic.

The cab driver is very excited and says,
Yes, I am single and Im Catholic too!

The nun says, OK, pull into the next alley.

He does and the nun fulfils his fantasy.

But when they get back on the road, the cab driver starts crying. My dear child, why are you crying? says the nun.

Forgive me sister, but I have sinned, says the cabby. I lied. I must confess, Im married and Im Jewish.

The nun says, Thats OK. My name is Kevin and Im on my way to a Halloween party.
