Meant to serve as a critique of the perfect, unrealistic families often seen on network TV, Married... With Children constantly pushes the envelope with its bathroom humor and over-the-top sexual innuendo. Al's sexist references to "hooters," demeaning homosexual stereotypes, and allusions to masturbation are comedic staples throughout the series -- as is Peggy's non-stop whining about never getting any sex from Al. The Bundys are also are constant schemers and don't hesitate to take advantage of each other if it helps them get ahead.
But even though the show comes across as being anti-"family values" on the surface, it actually supports the idea of a family that, while seriously flawed, cares deeply about each other. Al is vocal about "liking his family," while Peggy is very clear about the love she feels for her husband. The kids, while often embarrassed by their father, are always there to support him when it counts, and both siblings defend each other against others despite their constant rivalry. As a result, while the Bundys may not be perfect, the importance and strength of family is a strong theme throughout the series.
