Dinosaurs, the series about the Sinclairs, a family of anthropomorphic dinosaurs, ran for four seasons on ABC -- and, believe it or not, was actually not the most WTF show on TGIF (looking at you, Aliens in the Family). Of course the breakout star of the show was Baby Sinclair, who had several catchphrases, the most memorable being "Not the Mama!" which he would sling at anyone who was, in fact, not the mama.

Fun fact: Jessica Walter (aka Lucille Bluth from Arrested Development) voiced mama herself, Fran Sinclair. Kevin Clash, who was the longtime voice of Elmo, voiced Baby Sinclair.
