Sometimes American sitcoms are founded on a running gag.
A shoe salesman's house:Al Bundy is a fictional character and the main protagonist of the American television series Married... with Children.[1] Played by Ed O'Neill, Bundy is a misanthropic, working-class father of two who is portrayed as a somewhat tragicomedic figure. Although he is a born loser who constantly laments his lot in life, he nevertheless stands by his family, displaying wit, self-sacrifice and resilience in times of crisis.
He works as a shoe salesman at the fictional Gary's Shoes and Accessories for Today's Woman in the fictional New Market Mall. Al hates his job, loses it several times throughout the series, yet always ends up coming back to it. There is a running joke throughout the show that Al makes minimum-wage.
