Seeing as there appears to be a religious streak to the jokes lately:
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 and he replies, "I have a question to ask you, but I don't want to offend you.
She answers, 'My dear son, you cannot offend me. When you're as old as I am and have been a nun a 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 French kiss me."
She responds, "Well, let's see what we can do about that, however there are two things I need to be assured of first #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 "OK, pull into the next alley."
He does and the nun fulfils his fantasy. But when they get back on the road, the cab driver starts sniggering.
"My son, said the nun, what are you sniggering at?"
"Forgive me sister, but I have sinned - I lied, I must confess, I'm married and I'm Jewish my name's Hymie."
The nun says, "Oh that's OK, my name's Kevin and I'm on my way to a Halloween party."
