Chattering teeth (toy)

Chattering teeth, sometimes called chattery teeth, are a wind-up toy invented by Eddy Goldfarb mimicking the bodily function of the same name.

Originally named "Yakity Yak Talking Teeth", Goldfarb and Marvin Glass sold it to novelty company H. Fishlove & Co. who released it in 1949.

Reproductions are today sold at novelty stores.

While some chattering teeth are equipped with walking feet, many models are not.

H. Fishlove & Co., now a division of Fun, Inc. — a manufacturer of magic trick and novelty items — still produces chattering teeth based on Goldfarb's specifications.
