The fourth season of the television series Married... with Children aired on Fox from September 3, 1989 to May 13, 1990.

In the episode "It's a Bundyful Life (Part 2)," Ted McGinley makes a guest appearance as Norman Jablonsky before reappearing as a regular cast member in the next season as Jefferson D'Arcy.

Al decides to get a new car, but finds out that Peggy spent all his saved-up money that he buried in the backyard.

Al challenges the family to go out and make their own money so he doesn't get shaken down for his meager change every allowance day, prompting Peg to open her own tollbooth and Kelly to get a job as the eye candy in a rock video by The Gutter Cats (guest starring as themselves).

When Al discovers that Peg has been spending money on old junk from yard sales, the Bundys have one of their own...then turn it into a cheap carnival when no one buys what they're selling.
