She answers, "My dear 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 too!"
"OK" the nun says "Pull into the next alley"
He does and 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 sister, but I have 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 on my way to a Fancy Dress party."
