Mrs. Partington's Carpet-Bag of Fun: Crow Eating
Crow Eating 

A worthy old farmer residing in the vicinity of Lake Mahopack, was worried to death last summer by boarders. They found fault with his table, and said he had nothing fit to eat.

"Darn it," said old Isaac, one day, "what a fuss you're making. I can eat anything."

"Can you eat a crow?" said one of the boarders.

"Yes I kin eat a crow!"

"Bet you a hat," said the guest.

The bet was made, the crow caught and nicely roasted, but, before serving up, they contrived to season it with a good dose of Scotch snuff. Isaac sat down to the crow. He took a good bite, and began to chew away.

"Yes, I kin eat crow! (another bite and an awful face,) I kin eat crow; but I'll be darned if I hanker after it."
