How does the hot wife/foolish husband formula work in sitcoms?

You know what I’m talking about. Shows like The King of Queens and Everybody Loves Raymond, where the wife is attractive, smart, and rational while the husband is either fat, dorky, irrational or unattractive (or a combination).

What makes this good televsion? Does it allow for funnier set ups? Is this the main way to make funny sitcoms? How has it influenced society?

What are some other sitcoms that follow this formula? Does it still work?

How about a sitcom that doesn’t, but is still funny? How is it able to generate laughs?

Bonus: What is your favorite sitcom that uses the hot wife/foolish husband forumula?
