When she asked him why, he said, "I want to ask you something, but I don't want to offend you."
She said, "You can't offend me. I have been a nun long enough that I have heard just about everything."
The cab driver then said, "Well, I've always had a fantasy to have a nun give me a blow job."
She said, "Well, perhaps we can work something out under two conditions. You have to be single, and you have to be Catholic."
Immediately the cab driver said, "Oh, yes! I'm single and I'm Catholic!"
The nun said, "Okay, pull into that alley."
The cab driver pulled into the alley and the nun went to work. Shortly afterwards, the cab driver started crying.
The nun said, "My child, what's the matter?"
He said tearfully, "Sister, I have sinned. I lied, I lied...I'm married and I'm Jewish!"
The nun replied, "That's okay. My name's Bruce and I'm on my way to a costume party!"
