Originally called “Chalmers vs. Skinner,” the two-minute-and-48-second piece was part of an unusual episode of The Simpsons that aired during the show’s seventh season, on April 14, 1996. While most episodes of The Simpsons focus on the show’s titular family, “22 Short Films About Springfield” was different, as it was broken up into a series of short segments focusing on Springfield’s supporting characters. “Steamed Hams” — as “Chalmers vs. Skinner” would later come to be known — was simply one of those segments.
