Joke: A doctor specializing in circumcision retires after 30 years on the job. He kept all of the foreskins from all of the circumcisions he has ever performed. In remembrance of his career, he goes to a leathersmith and tells him to make something out of them.

A week later he presents the doctor with a wallet. The doctor asks him, "This is all you could make out of all of those foreskins?"

The leathersmith replies, "It's kinda cold in here. Stroke it a little and you'll have yourself a briefcase."
