The Chattering Teeth joke has been around for many years. These are the wind up version that you wind up to start the chopping of the teeth. Just wind these up and they will be chattering away! Great gag to place on a table when they talk to much or place in a lunch pail or bag and when they take them out they will start to chatter. Classic practical joke item for your box of pranks and gags.
