The Nun's Kiss

A cabbie picks up a Nun. She gets into the cab, and the cab driver won't stop staring at her. She asks him why is he staring.
He replies, "I have a question to ask you, but I don't want to offend you."
She answers, "My 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 kiss me."
She responds, "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!"
"OK," the Nun says. "Pull into the next alley."
The nun fulfills his fantasy with a kiss that would make a hooker blush. But when they get back on the road, the cab driver starts crying.
"My dear child, said the nun, why are you crying?"
"Forgive me but I've sinned. I lied. I must confess, I'm married and I'm Jewish."
The nun says, "That's OK, my name is Kevin and I'm going to a Halloween party."
