Al Bundy is an unsuccessful middle aged shoe salesman with a miserable life and an equally dysfunctional family. He hates his job, his wife is lazy, his son is dysfunctional (especially with women), and his daughter is dim-witted and promiscuous.
Bud asks Al to repair the basement after Al starts charging him rent. When Al refuses, Bud calls a health inspector who makes Al live in the basement after it is deemed uninhabitable.
