A cab driver stops to pick up a nun in a rather seedy neighborhood. As she gets into the cab the cabbie catches a flash of thigh peeking out from underneath her habit. The cabbie gets to thinking, "Hummm, I wonder?" So he asks the nun, "Sister, do nuns think about sex?" The nun answered, "Well, certainly. But we are the brides of Christ, so until that day, we abstine."
The cab then asks, "Well, can you kiss?" And the nun responds, "Well, I see nothing wrong with a kiss." Emboldened the cabbie asks the Nun for a kiss.
The nun tells the cabbie, "I would only kiss a man who is a devout Catholic, has never been married and has no children." The cabbie smiles and says, "You're in luck Sister, I'm a devout Catholic, have no children and have never been married."
So the nun gives the cabbie a full on wet kiss.
As they pull up to the Nun's stop, the Cabbie stricken with guilt says, "Sister, I lied to you. I'm really a married Baptist with 4 children. Will you please forgive me? You see since I was young, I've had this fantasy about Nuns." The Nun looks over her shoulder and says, "Of course I'll forgive you, if you forgive me. You see, actually my name is Steve and I'm on my way to a costume party.""
