Jack Crowder (later billed as Thalmus Rasulala) guest stars as Chester Byrd, a high-pressure black real estate agent. Offering to give Archie twice what he paid for his house, Byrd adroitly and insidiously utilizes scare tactics, warning the Bunkers that their neighborhood is about to be infested by low-income African-Americans. Though Archie takes Byrd at face value, Lionel recognizes the "blockbuster" for what he is. Scripted by Austin and Irma Kalish, Michael Ross, and Bernie West from a story by the Kalishes, "The Blockbuster" originally aired on November 13, 1971. ~ Hal Erickson, Rovi
