A nun gets into the cab, and the cab driver won't stop staring at her.
"I have a question”, he says, “but I don't want to offend you".
"My son, you cannot offend me. When you're as old as I am and have been a nun as long as I have, I'm sure that there's nothing you could say that I would find offensive."
"Well, I've always had a fantasy to have a nun kiss me."
"Well, let's see what we can do about that. But first, you have to be single and you certainly must be Catholic."
The cab driver gets very excited and says, "Yes, yes! I'm single and Catholic!"
"Okay then" the nun says. "Pull into the next alley and we’ll see what we can do."
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 so upset?"
"Forgive me, but I've sinned. I lied. I must confess, I'm married and I'm Jewish!"
The nun says, "Oh, that's okay, my name is actually Barnard and I'm going to a Halloween party."
