Chapi Chapo (chapeaux, in french means "hats") was a stop-motion French short series created in 1974. The music and them song is so catchy. I have found myself singing it several times in my life. The main characters, Chapi and Chapo, move around as if locked in a Atari game. It hit the American scene in the 1980's on the Nickelodeon show Pinwheel. Yes, yet another childhood theme song that I just can't shake......and I dont know if I ever want to.
