A cabbie picks up a nun, and as she gets into the cab, she notices that the very handsome cabbie won't stop staring at her in his rear view mirror. She asks him why he is staring.
He replies, "I have a question to ask you, but I don't want to offend you."
The nun responds, "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. There's nothing you could ask that I will find offensive."
The cabbie says, "Well, I've always had a fantasy to have a nun kiss me."
She responds, "Let's see what we can do about that, but one, you have to be single, and two, you have to be Catholic."
The cabbie excitedly answers, "Yes, I'm single and Catholic!"
The nun tells him to pull into the next alley, and she fulfills his fantasy with a passionate kiss. When they get back on the road, the cabbie begins to cry.
"My dear child", the nun says, "why are you crying?"
"Forgive me, sister, but I have sinned. I lied. I'm married, and I'm Jewish."
The nun replies, "That's okay - my name is Kevin, and I'm on the way to a Halloween party."
