Premise: A long-running sitcom about a Park Avenue millionaire who adopts two Harlem orphans after the death of their housekeeper mother. The younger brother, Arnold, was an immediate hit, and the precocious lad's frequent query of his sedate, older brother---'Whatchutalkinbout, Willis?'---entered the pop-culture lexicon. The sitcom, on the air for eight years, spun off 'The Facts of Life.'
