The very funny put-down of a lizard who is best at only one thing: opening his big mouth. Every feat Sam brags of, Pete can match (catching one, two, three flies on the fly, becoming brown, becoming green, becoming brown and green) until Sam tries to turn himself all the colors of the funny papers, and fails. Then Pete scores: ""I know that lizards like us can only be brown or green. . . . If you were the best lizard there is, you would know it too."" Slightly slapstick cartoons make the most of Sam's discomfiture and Pete's satisfaction.
