A cab driver picks up a beautiful nun. He won't stop staring at her. She asks what's wrong. She says he can tell her anything.

He says he's sorry, but he's always had fantasies about nuns - wanted to be kissed by one.

She tells him it's all right. But she just has two questions: Is he Catholic, and is he single?

He tells her he is Catholic, and he is single.

"Okay" she says "Pull into the next alley".

They pull into an alley and the nun fulfils his fantasy with a kiss that would make a hooker blush.

When they've finished, the man's crying. She asks him what's wrong?

"I'm sorry" he says "I can't lie to you. I'm married, and I'm Jewish".

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