"You are old," said the youth, "and your jaws are too weak
For anything tougher than suet;
Yet you finished the goose, with the bones and the beak --
Pray, how did you manage to do it?"
"In my youth," said his father, "I took to the law,
And argued each case with my wife;
And the muscular strength which it gave to my jaw,
Has lasted the rest of my life."
-- Lewis Carroll, "Alice's Adventures in Wonderland"
