Before Scott Baio was 45 . . and Single, he was "Charles," a college student who lived in a basement and babysat the kids of the house to earn his keep. The plot sounds normal until you hear the show's theme song: "Charles in charge of our days and our nights. Charles in charge of our wrongs and our rights . . . I want Charles in charge of me." What the hell kind of underground cult was this dude running with his ugly '80s clothes and authoritarian politics? That is the question.
