TOYOTA • People Person Agency: Saatchi & Saatchi, Los Angeles Click to view Let's start off with a real monstrosity. Did you find the giant Toyota Prius person, made up of lots of normal-size people, to be delightfully enchanting? Or did you find him utterly terrifying? Saatchi & Saatchi Los Angeles came up with the idea for the creature—a Pilobolus-like beast formed by 18 people linked together, reminiscent of the artwork of Andre Martins de Barros. He was meant to be fanciful, but many found him objectionable. "I'd say the worst part was the nose being someone's butt," wrote one reviewer. "Reminds me just a tad of the Human Centipede."

ZIPPEARZ • Rhythm & Boobs Director: David Gott Click to view Here's one of the more anatomically strange ads of the year. This spot for Zippearz earbuds featured a female jogger whose breasts got frighteningly auto-jiggly with the funky dance beat, much to the dismay/curiosity of a dude sitting nearby on a park bench. "They won't fall out," explains the just-as-crass female voiceover, which is all breathy and sultry—referring to the earbuds, obviously. Not the proudest moment for tech advertising, but certainly a visual that sticks with you.

CARMAX • Kid in a Candy Store Agency: Amalgamated, New York Click to view The most mind-bending commercial from Super Bowl XLV last February, this CarMax spot had a peculiar cast of characters: a kid in a candy store, a geek at a robot convention, a mermaid at a swim meet, a wrestler in a folding-chair factory, a hippie in a drum circle, an acrobat in a mattress store, and of course, a customer at CarMax—lucky souls, all, who feel right at home in their environments. All that was missing, really, was the proverbial pig in muck.

SONIC • Heart's Desire Agency: Goodby, Silverstein & Partners, San Francisco Click to view This spot isn't really freaky so much as it is completely awesome. But it descends into a hallucinatory phantasmagoria, so it counts. It opens with a man at a Sonic drive-through being told he can get anything he wants on his burger. This sends him careening into a colorful, crazy daydream full of giant Sonic food floating around and Sonic workers making kaleidoscopic Busby Berkeley moves in roller skates. (The Dude's dream sequence in The Big Lebowski reportedly was an inspiration.) The music tops it off—a parody of "You Can Do Magic" by America, with lyrics that are stupidly and comically forced to rhyme. Throw in some wonderfully goofy acting, and you've got the year's looniest fast-food ad. I'll have what he's having.
