I agree, except that it has always been A pattern in sitcoms. But now it seems to be the pattern for MOST sitcoms. I call these types of sitcoms the “fat guy, hot wife” sitcoms. The orginal was the Honeymooners, which if you haven’t seen them were very funny. Raymond is one, King of Queens, Simpsons, Family Guy, that one with Belushi, the list goes on. The guy is usually but not always fat, but the wife is almost always very attractive, and always portrayed as smart, and kind, and correct, while the guy is silly, childish, etc.
Why is this? People think its funny, I guess.
