A surgeon was retiring from his long and rewarding career as a specialist in circumcision. Throughout his career, he had saved the foreskins of his patients in specimen jars as momentous, and now wished to fashion them into a souvenir.
So he brought his hundreds of specimens to a leathersmith, and asked him to craft them into an article of fine artistic quality.
"I'll see what I can do," said the artisan, "Check back with me in one week."
The surgeon returned one week later, eager to see what magnificent article the leathersmith had made for him. The leathersmith presented him a wallet.
"All those foreskins and you only made me a wallet?" exclaimed the surgeon.
The leathersmith replied "Yes, but if you stroke it, it becomes a briefcase."
