The nun and the cabbie
A nun is catching a cab in New York on night. The nun gives the cabbie directions, and the cabbie takes off. After a few blocks, the cabbie says to the nun, "Sister, I know that you have holy vows and all, but I've always fantasized about kissing a nun, can I kiss you?" The nun looks at the cabbie and says "only if your lips are pure and have not touched a woman". The cabbie looks back at the nun and says "yes sister, my lips are pure and have not touched a woman". The nun nods, and the cabbie plants a wet kiss on the nun. The cabbie then tells the nun, "sister, I feel bad. I lied to you, my lips are not pure, I have touched a woman". The nun looks back and says, "hey man, that's ok, I lied too, my name is Chuck and I'm just on my way to a costume party".
