Family Guy:
Season:     6     / Episode:     7    
Peter's Daughter

The show is set in the town of Bedrock in the Stone Age era. The show is an allegory to American society of the mid-20th century; in the Flintstones' fantasy version of the past, dinosaurs, saber-toothed tigers, woolly mammoths, and other long extinct animals co-exist with barefoot cavemen, who use technology very similar to that of the mid-20th century, although made entirely from pre-industrial materials and largely powered through the use of various animals. The characters drive cars made out of stone or wood and animal skins and powered by foot.

Peter's sister Karen (voice of Kate McKinnon) visits the Griffins, and turns out to be a bully who treats Peter the way he treats Meg. Although Meg is initially amused, she eventually feels bad and decides to help Peter train to beat Karen in a wrestling match. Meanwhile, Stewie and Brian decide to go on a cleanse to avoid eating too much on Thanksgiving.
