Appearances Can Be Deceiving

One day a nun was standing on the side of the road waiting for a cab. A cab stopped and picked her up. During the ride she noticed that the driver was staring at her. 

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!"
