There are quite a few anime, manga, and JRPGs that have a character who, at one point, offers to (or in some cases has to) cook for the other characters and is often convinced they are at least decent. They end up poisoning the others by mistake. It's often played for laughs that this person is shockingly bad, but (often) completely unaware. Usually, this person is a woman or girl. It's mildly amusing,(citation needed) but it happens in so many stories, it seems any show going long enough needs to have this joke in it.

What is it about this joke that it is so often repeated in manga and anime (and games, I guess)? Is there some cultural thing I'm missing making it funnier? (As a sub-question, why is it nearly always women?)
