Kingpin

I say to my buddy, "You are driving down the street when you see a stop sign. As you stop, you see a hammer lying on the ground next to the sign. When you finally start driving again, you see a tower in the distance with a clock on it. What is the first thing you think of?" And guess what he responds with? He said, "I think penis."

Any alchemists out there that can help a beginning alchemist?
