A guy decides to quit smoking. He decides to use the nicotine patch, but thinks it looks ridiculous.
Later in the week, he stands at a urinal beside his co-worker. The co-worker looks down and notices the man has a nicotine patch on his penis.
Horrified, the co-worker says, "That's disgusting! Why in the world would you put a patch on your d**k?"
The man replies, "Don't knock it -- I'm down to two butts a day."
