Biting-the-Hand Humor (https://tvtropes.org/pmwiki/pmwiki.php/Main/BitingTheHandHumor). It's when the creator(s) of a work make(s) jokes at the expense of the company funding that work, i.e. "biting the hand that feeds them". It can happen when an embittered creator, or one cynical of the morality of the entertainment industry, inserts into their work a thinly disguised slap to the face of the company that employs them, usually for unsatisfactory royalties or advance payments.

Here is a perfect example: Any time the FOX Network is mentioned on The Simpsons or Family Guy.

Who else here on Sitcoms Online gets a good laugh anytime a program's network is referenced on that program?

I liked when Jon Voight bit Kramer’s hand
