A bobblehead doll, also known as a bobbing head doll, nodder, or wobbler, is a type of collectible toy. Its head is often oversized compared to its body. Instead of a solid connection, its head is connected to the body by a spring or hook 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 breakfast cereal mascot Count Chocula, beat generation author Jack Kerouac, and Nobel-prize-winning geneticist James D. Watson, the figure is most associated with athletes, especially baseball players. 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.

The earliest known reference to a bobblehead is thought to be in Nikolai Gogol's 1842 short story The Overcoat, in which the main character's neck was described as "like the necks of plaster cats which wag their heads". The modern bobblehead first appeared in the 1950s. By 1960, Major League Baseball had gotten in on the action and produced a series of papier-mache bobblehead dolls, one for each team, all with the same cherubic face. The World Series held that year brought the first player-specific baseball bobbleheads, for Roberto Clemente, Mickey Mantle, Roger Maris, and Willie Mays, still all with the same face. Over the next decade, after a switch in materials from papier-mache to ceramic, bobbleheads would be produced for other sports, as well as cartoon characters. One of the most famous bobbleheads of all time also hails from this era: The Beatles bobblehead set, which is a valuable collectible today. By the mid-1970s, though, the bobblehead craze was in the process of winding down.

"Pumped Up Kicks" is a song by American indie pop band Foster the People. It was released as the group's debut single in September 2010, and the following year was included on their EP Foster the People and their debut album Torches. "Pumped Up Kicks" became the group's breakthrough hit and was one of the most popular songs of 2011. The song was written and recorded by frontman Mark Foster while he was working as a commercial jingle writer. Contrasting with the upbeat musical composition, the lyrics describe the homicidal thoughts of a troubled youth.

The track received considerable attention after it was posted online in 2010 as a free download, and it helped the group garner a multi-album record deal with Columbia Records imprint Startime International before they had issued a commercial release. The song became both a crossover hit and a sleeper hit in 2011, as it received significant airplay on modern rock and contemporary hit radio stations. The song spent eight consecutive weeks at number three on the Billboard Hot 100 chart in the United States, making it the first Billboard Alternative Songs number-one single to crack the U.S. top 5 since Kings of Leon's "Use Somebody" in 2009. The song was widely praised by critics, and it has been licensed for use in a wide range of popular media since its release. "Pumped Up Kicks" received a Grammy Award nomination for Best Pop Duo/Group Performance.
