The joke maker's association had a feast. They exploited their humorous
abilities, and all made merry, save one glum guest. At last, they
insisted that this melancholy person should contribute to the
entertainment. He consented, in response to much urging, to offer a

"What is the difference between me and a turkey?"
When none could guess the answer, the glum individual explained:
"I am alive. They stuff turkeys with chestnuts after they are dead."
