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.
In the third season opener, Al learns that he has had a copy of "The Little Engine That Could" since 1957 and when he goes to return it, he finds the same fat librarian that was there in 1957.
