I don't think the Post cereal people still make Crispy Critters but when I was a kid, they did…and their commercials featured Linus the Lionhearted, whose voice was supplied by producer-gangster Sheldon Leonard. Linus had his own cartoon show for a while (we showed you the opening here) and this is one of his catchier commercial jobs. Get ready to hum the Orange Moose song to yourself for the next few days.
