The routine practice of circumcision was part of a certain small town doctor's job, and he found himself reluctant to discard the foreskins. So he saved them all up in a jar of formaldehyde. Many years went by and the doctor decided to retire. As he was cleaning out his office he came across the jar, which by this time contained hundreds of foreskins. Again it seemed a pity to throw them away, especially after all this time. So the doctor took the jar to the tailor shop around the corner.

"Say, can you make something with these?" he asked.

"No problem," replied the tailor cheerfully after assessing the contents of the jar. "Come back in a week."

A week passed, and the tailor proudly presented the doctor with a nice wallet.

"Now wait just a minute," protested the doctor. "It's very nice, but there were literally hundreds of foreskins in that jar. All I get to show for them is a measly wallet?"

"Calm down, Doc" the tailor said reassuringly. "Rub it a little bit it turns into a suitcase."
