The line between order and anarchy is as fine as a rabbit's whisker. Especially if you're watching Foster's Home for Imaginary Friends, whose namesake is managed by a large bespectacled hare named Mr. Herriman. The Foster home is a safe haven for imaginary friends abandoned by their creators, and for Bloo, a blobby wiseacre who is most certainly not abandoned by his best friend Mac. That is, Bloo isn't adopted out as long as Mac shows up every day at 3 o'clock on the dot.

Unfortunately, super-punctual Herriman doesn't just have a very important date; he has a Schedule. He'll sign the adoption papers if Mac's late by a quarter of an hour. Spoonfuls of food choo-chooing into mouths must adhere to a timetable. Frankie Foster, the proprietor's college-grad granddaughter, is rudely interrupted from her cozy waking dream. And in a move reminiscent of cranky DVR players, Herriman pulls the plug on the season finale of a Lost send-up! We'll never find out about those miniature hurricanes and trolls and unicorns now.

And so the disgruntled friends resort to Bloo's expertise in "Let Your Hare Down." With his beloved paddle-ball taken away, Bloo summons a rare burst of social responsibility and resolves to make Herriman loosen up.

Boy, does he ever. Foster's frenetic sight-gags are some of the best because they're rarely throw-aways. The combination of hand-drawn and vector animation is perfect for a clean style that nevertheless tumbles through a carnival, a TP'd house, a trampoline, and so on until Bloo and Herriman are cliff-jumping in Tijuana. When the stoic bunny finally breaks down and takes the leap, the ride's already drummed your funny bone.

Herriman changes his name to "Harry" and the whole house spirals into hippie stoner anarchy, or perhaps a cross between a rave and a frat party. Alas, we learn this cracked-out trip into the counterculture is also a "moral of the story" show, so enjoy it while you can. (Skater Herriman was my favorite.) Long-time fans will spot a few re-used jokes in the second half. Still, half a Foster's show is better than most toons in the last decade, and if you ever want to see Bloo streaking, you'll tune in. There's plenty more Foster's on the Cartoon Network and online. New ones are scheduled for Thursdays -- don't be late!
