There was this guy who wanted to quit smoking. He decided to use the patch to try to quit, but he was very self-conscious about it and thought that it looked ridiculous.
One day, the man was in a public bathroom standing at a urinal. He looked down at the guy standing next to him and noticed that he had a patch on his penis.

Puzzled, the man asked, "Why in the world do you have a nicotine patch on your dick?"

And the man replied, "Well, why not? It's working; I'm down to two butts a day."
