The song was part of a running gag throughout King Of The Hill
, an animated TV series set in the fictional town of Arlen, Texas. Mangione, who made several guest appearances on the show during its run from 1997 to 2010, portrayed himself as the reluctant celebrity spokesperson for Mega Lo Mart. When his strict contract with the department store takes over his life, he's reduced to living in secret at the Arlen location. The joke was that no matter what song Mangione played, it always turned into "Feels So Good."
Mangione first shows up in the season 1 episode "Luanne's Saga." Wearing his red-and-white jacket and trademark hat from the album cover, he appears in a commercial for Mega Lo Mart
, saying he shops there because it "feels so good."
