Peter Mink in "Settling A Dispute"

Now, when you stop to remember that Jimmy Rabbit was four times bigger than Peter Mink, you can understand how angry Peter must have been. He saw right away that such a thing was impossible. "I can't do that!" he cried.
"Then I declare the agreement to be broken," said Mr. Crow. "And I advise Jimmy Rabbit to run home at once, for I happen to know that his mother is looking for him." Afterward, Peter Mink always claimed that there was no use trying to get the better of anybody that had the left hind-foot of a rabbit. He said that they certainly were lucky, and that he knew what he was talking about.
