Excited claims such as these decorate the package of the The Yakity-Yak Talking Teeth, which made their official debut in 1950.  According to Collectors Weekly blogger Lisa Hix, in the 1940s, toy inventor Eddie Goldfarb saw an ad for a false-teeth holder called a “Tooth Garage” and envisioned a pair of dentures, “chomping and sputtering down the road like a car, and parking on their own.”

So in 1949, Goldfarb gave life to the wind-up gag commonly known as “chattering teeth,” brought them to toy legends Marvin Glass and Irving Fishlove (who introduced latex fake vomit to the world) and the rest is history.

Hix had this to say: “If you’re looking for an intellectual, rational reason why chattering teeth have been such a consistent seller and are repeatedly knocked off by overseas toy makers, there isn’t one. They look like dentures, which are inherently funny. They can startle the unsuspecting. And they’re right out of a dentistry nightmare, disembodied teeth and gums talking, shivering, running, and chomping on their own. It’s the stuff of late-night horror films and Saturday-morning cartoons.”
