Not everyone a caveman encounters in the future will be helpful, sympathetic, or even patient. Some will be downright menacing.

Time Machine
25 October 2015 | by (India) – See all my reviews

The Flintstones is an animated, prime-time American television sitcom that was broadcast from September 30, 1960 to April 1, 1966, on ABC. The show, produced by Hanna-Barbera, fancifully depicted the lives of a working-class Stone Age man, 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 Flintstones was the most financially successful network animated franchise for three decades, until The Simpsons debuted. In 2013, TV Guide ranked The Flintstones the second Greatest TV Cartoon of All Time (after The Simpsons).

The Flintstones and the Rubbles visit the Bedrock World's Fair, where they visit a time machine exhibit, where they travel to various times of the "future" (a caricature of Jack Benny is used in the "Nero" sequence). Notes: Officer Dibble from Top Cat makes a cameo appearance as a policeman from the future. The teaser is a scene from the middle of the episode.
