A cartoon double-bill on
NBC, originally airing in 1977.
Baggy Pants was a cat, somewhat, who was very similar in actions to the
Pink Panther, though also borrowing heavily from
Charlie Chaplin. Baggy Pants never spoke, but lead the laugh track through various gags using movements and expressions. The Nitwits were retired superheros who were called back to fight crime, resembling characters from
Rowan and Martin's Laugh In.
Basically, this was just another reason to wake up at 6AM on a Saturday morning cartoon day.
