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 momentos, and now wished to fashion them into
a souvenir.
So he brought his hundreds of specimens to a leathersmith, and
asked him to craft 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 make me a wallet?"
exclaimed the surgeon.
The leathersmith replied "Yes, but if you stroke it, it
becomes a briefcase."
