Chattery Teeth
Chattering Teeth are a children's wind-up toy invented by Eddy Goldfarb. Originally called "Yakity Yak Talking Teeth", Goldfarb and Marvin Glass sold it to novelty company H. Fishlove & Co. who released it in 1949. The Yakity Yak Talking Teeth are a pair of mechanized teeth are wound up at the back, and the teeth clatter together. Reproductions are today sold at novelty stores. While most chattery teeth come equipped with walking feet, many models do not.
Goldfarb's original design was awarded from the U.S. Patent Office. H. Fishlove, now a division of magic trick and novelty manufacturer Fun Inc., still produces chattery teeth based on Goldfarb's specifications.
Chattering Teeth are also commonly seen in toy shops in cartoons.
The Toy is used as the logo for Rooster Teeth alongside a silhouette of a Rooster.
