A bobblehead doll, also known as a bobbing head doll, nodder, or wobbler, is a type of collectible doll. Its head is often oversized compared to its body. Instead of a solid connection, its head is connected to the body by a spring in such a way that a light tap will cause the head to bobble, hence the name.
Although bobblehead dolls have been made with a wide variety of figures such as vampiric cereal pitchman Count Chocula, beat generation author Jack Kerouac, and Nobel-prize-winning geneticist James D. Watson most associated with athletes, and baseball players in particular. Bobblehead dolls are sometimes given out to ticket buyers at sporting events as a promotion. Corporations including Taco Bell (the 'Yo Quiero Taco Bell' Chihuahua) , McDonald's (Ronald McDonald), and Empire Today (The Empire Man) have also produced popular bobbleheads of the characters used in their advertisements.
