Baby Sinclair was the breakout character of Dinosaurs, the Jim Henson family sitcom that aired on ABC from 1991 to 1994 and followed a family of anthropomorphic dinosaurs. Voiced in English by Kevin Clash, the baby became famous for hitting his father with a pan and insisting he was not the mama. The Spanish dub turned that catchphrase into no la mama, preserving the same whiny rhythm. Clips and soundboard rips of the line later circulated among Latin American audiences, keeping the joke alive as a nostalgic reaction sound.
