Garfield by Jim Davis for May 19, 1989
Transcript:
Jon: Diet gotcha down, Garfield? Garfield: I'm lower than a snakes belly in a wagon rut. I have about as much chance of surviving this diet as a one-legged opossum on a freeway. Jon: Why, soon, you'll be skinnier than a string bean in a pumpkin patch. Garfield: That's the stupidest thing I've ever heard.
You really needed to go on a diet though. You’re fatter than a pregnant hippopotamus after Christmas dinner.
