5. Tony Little’s Gazelle

The sight of muscle-bound, ponytailed fitness pro Tony Little trotting away on his Gazelle and screaming about how much he was working his “but-tocks!” in this 2001 infomercial definitely raised some eyebrows. But when Tony mounted the Gazelle behind Darla Haun and started riding with her to prove the machine could hold both their weights, this infomercial started to look a lot like a soft-core porn video. The close-up shots of women’s behinds in tight workout shorts and men’s naked torsos only added to the image. Whether it was because of the sexy come-on, or the screaming chants of “Yeah baby,” Tony had our attention.

4. Magic Bullet

You’ve got to love the storyline of the Magic Bullet infomercial: A couple, Mick and Mimi, invite a few friends over for a party. The next morning, they all gather in the kitchen (which looks suspiciously like a television studio) for breakfast. Their friend Berman staggers in hungover, wearing last night’s clothes. A frumpy woman in a housedress named Hazel shuffles in with a cigarette dangling from her mouth.

Mick and Mimi are surprisingly perky, considering the state of their guests. They proceed to entertain their friends with the wonders of a tiny, bullet-shaped food processor called the Magic Bullet. While the guests look on in utter amazement and delight, the Magic Bullet whips smoothies, grinds coffee, mixes muffins and scrambles omelets — and that’s just the appetizer. Every dish is perfectly prepared in just 10 seconds or less. Sounds too good to be true, but millions bought the message. The $60 Magic Bullet brought in nearly a quarter of a billion dollars in sales in just over a year. The infomercial has been translated into dozens of languages and has been sold in 60 different countries .

3. Stop the Insanity!

With her blonde hair cut shorter than a drill sergeant’s, and her throaty yell urging everyone to “Stop the insanity!” Susan Powter became an infomercial icon. Dubbed the “Lenny Bruce of Wellness,” Powter ranted against the ills of dieting and urged us that there were no fat people — just unfit people who maybe had a little extra around the middle. After her reign in the early 1990s, Susan disappeared from the radar, but today this diet and fitness guru is back. She’s still got the spiky do, but the message has been toned down a bit. Instead of stopping the insanity, now Powter just wants us to “Eat, breathe, move and think.” Sounds pretty easy.

2. ThighMaster

After five years of playing the ditzy Chrissy Snow on “Three’s Company,” followed by a few lesser-known roles, it looked like Suzanne Somers’ career had come to a crashing halt. Then along came the infamous infomercial with the famous shot of Somers sitting on a couch, squeezing a butterfly-shaped exercise device between her thighs. The spot had men salivating and women reaching for their purses. Though the ThighMaster became major fodder for late-night talk show hosts (David Letterman featured it on one of his “Top 10″ lists), Somers had the last laugh, selling some 10 million ThighMasters in 120 countries around the world [sources: Piccalo and McGinn]. She turned her infomercial run into a veritable empire, churning out 300 different products, including jewelry, skin care items and clothing. Who knew Chrissy would turn out to be such a brilliant businesswoman?

1. Ronco GLH Formula #9 Spray-on Hair

­There’s nothing funny about going bald (as anyo­ne who’s experienced it will probably attest), but when the hair replacement comes out of a spray can, things get downright hilarious. Infomercial king Ron Popeil (who also brought us such notable products as the Pocket Fisherman and Veg-O-Matic) hosted this spot for GLH Formula #9, which supposedly restores the appearance of a full head of hair with just a few quick sprays. To prove it, Popeil pulled a few hair-impaired people randomly from the audience, and suddenly their bald spots were — well, covered in spray paint. Is it really a surprise that Popeil’s former company, Ronco, went bankrupt in 2007?
