A cornerback (CB) (also referred to as a corner) is a member of the defensive backfield or secondary in American and Canadian football. Cornerbacks cover receivers, to defend against pass offenses and make tackles. Other members of the defensive backfield include the safeties and occasionally linebackers. The cornerback position requires speed and agility. Since shorter players tend to be more agile than taller players, cornerbacks are typically among the shortest players on the team. A cornerback's skillset typically requires proficiency in anticipating the quarterback, back-pedalling, executing single and zone coverage, disrupting pass routes, shedding blockers, and tackling.

The chief responsibility of the cornerback is to defend against the offense's pass. The rules of American professional football and American college football do not mandate starting position, movement, or coverage zones for any member of the defense. There are no "illegal defense" formations. Cornerbacks can be anywhere on the defensive side of the line of scrimmage at the start of play, although their proximity, formations, and strategies are outlined by the coaching staff or captain.

The Flintstones is an animated, prime-time American television sitcom that was broadcast from September 30, 1960 to April 1, 1966, on ABC. The original pilot episode clip however was called the "Flagstones" (which first appeared in 1959 as a 90 second promotion to draw advertisers to the show) and was later reincorporated into the show's 1st episode (3rd episode in original airdate order). The show's name was changed to "The Flintstones" shortly thereafter. The show was produced by Hanna-Barbera Productions, The Flintstones was about a working class Stone Age man's life with his family and his next-door neighbor and best friend.

The show's continuing popularity rested heavily on its juxtaposition of modern everyday concerns in the Stone Age setting.

The show is set in the Stone Age town of Bedrock. (In some of the earlier episodes, it was also referred to as "Rockville"). In this fantasy version of the past, dinosaurs, saber-toothed tigers, woolly mammoths, and other long-extinct animals co-exist with cavemen. Like their mid-20th century peers, these cavemen listen to records, live in split-level homes, and eat out at restaurants, yet their technology is made entirely from pre-industrial materials and largely powered through the use of various animals. For example, the cars are made out of stone, wood, and animal skins, and powered by the passengers' feet (as in the theme song, "Through the courtesy of Fred's two feet").
