ThighMaster
Suzanne Somers in a leotard, squeezing a blue-and-white spring between her knees, and the promise that you could squeeze your way to shapely hips and thighs. The ThighMaster infomercial ran so often in the early 90s that the thing was a punchline before most people owned one, and then they bought one anyway: more than 10 million of them.
