"The Flintstones" is an American animated sitcom produced by Hanna-Barbera Productions. The series takes place in a romanticized Stone Age setting and follows the activities of the titular family, the Flintstones, and their next-door neighbors, the Rubbles. It was originally broadcast on ABC from September 30, 1960, to April 1, 1966, and was the first animated series to hold a prime-time slot on television.

In that series, there is a quarry that is owned and operated by the no-nonsense Mr. Slate. Fred and Barney are both Bronto-crane operators who drive brontosauruses to create gravel at Slate Rock and Gravel Company (also known as Rockhead and Quarry Cave Construction Company in earlier episodes)

Sometimes the duo isn't so good at their jobs, though — Fred has been fired by Mr. Slate on multiple occasions, only to earn his job back every time.
