12. Garfield and Friends (CBS, 1988-1994)
Based on Garfield, Jim Davis' comic strip about a fat, lazy, and mean-spirited Tabby cat, this long-running series is a cartoon classic. Garfield's "friends" included not only strip regulars like his bumbling cartoonist owner Jon, Jon's dim-witted dog Odie, and vain kitten nemesis Nermal, but also introduced a cast of curious farm animals on the spin-off U.S. Acres, which featured well-read OCD swine Orson, and Wade, a bitch-made duck who wears a flotation device.
The jokes seem pretty simple to us now, but with three cartoon segments and several shorts packed into a half hour, it was perfect for our new ADD generation to snort Ritalin to.
