Appendix ?  Reminds me of a story-

A newly ordained rabbi was so filled with the sacredness of the act when he performed his first bris that he saved the foreskin.

He asked about the foreskins and the rabbi explained how he happened to have them. The leather guy persuaded the rabbi to let him have the foreskins, promising he would make something out-of-them. A week later, he returns and presents the rabbi with a beautiful hand-tooled/stitched/ engraved/dyed wallet of the highest quality. The rabbi had never seen anything so beautiful and said to his friend " How much do I owe you ? " (hoping to get a freebee) The leather guy without batting an eye replied - " $350 bucks. " 
The rabbi said " Too much for just a wallet " 
The leather guy said - " But this is no ordinary wallet - If you stroke it - it becomes a suitcase ! "
" Sold " the rabbi said....
