This is actually true for most comedy shows. Like you said, men do idiot stuff and women pull them back on track / are the voice of reason.

I believe this comes from two reasons:

- We are more inclined to believe men try and do dumb stuff. And we're more receptive, culturally, to men having "bad traits".

- TV's main demographic is women. Therefore, the "relatable character" ends up being a woman.
