Captain Caveman originated in Captain Caveman and the Teen Angels, the Hanna-Barbera animated series that premiered in 1977. Voiced by Mel Blanc, the thawed-out prehistoric superhero solved mysteries with the Teen Angels while shouting his name as a battle cry. The yell became his signature gag, repeated in later Hanna-Barbera crossovers and reruns for decades. It survives online alongside other classic cartoon sounds like the Woody Woodpecker Laugh, used whenever creators need instant nostalgic, over-the-top heroic energy.
