Circumcision?

Theres this guy and he has been doing circumcisions for the past 30 years. he has kept the skins as a souviner, so he has a couple of thousand of them. he decides he will pack it in and retire, but he wonders what he will do with his souviners. he goes to a guy that makes leather hand bags, and tells him what he has been doing for the past 30 years, and that he wants him to make something out of them so that it will remind him of his important job and great skill. he is told to come back in 2 weeks. when he arives back at the shop the leather tanner hands him a wallet. .the gut looks at it and says," i have collected skins for 30 years and all you made from the big pile i gave you is a small wallet ", and the leather tanner says, "eh, when you rub it, it turns into a suite case"
