A nun gets into a cab and the cab driver won't stop staring at her.
She asks him why is he staring.

"I have a question to ask you but I don't want to offend you."

"My dear son, you cannot offend me. When you're 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. I'm sure that there's nothing you could say or
ask that I would find offensive."

"Well, I've always had a fantasy to have a nun perform oral sex on
me."

"Well, let's see what we can do about that: 1) you have to be single
and 2) you must be Catholic." The cab driver is very excited and says,
"Yes, I am single and I'm Catholic too!" The nun says, "O.K., pull
into the next alley." He does and the nun fulfills his fantasy. But
when they get back on the road, the cab driver starts crying his eyes
out.

"My dear child, why are you crying?"

"Forgive me, sister, but I have sinned. I lied, I must confess. I'm
married and I'm Jewish!"

"That's okay,'' says the nun. ''My name is Kevin and I'm on my way to
a Halloween Party."
