It should be obvious from the context (Itchy and Scratchy, Lisa, Bart), but for those who did not understand*, what boone describes in his write-up is part of an episode from The Simpsons TV show (in other words, this node is YASQ).

Mattel is a real toy brand IRL, as well as Mars is a real chocolate bar brand.

This Simpsons episode, while advertising in a strange way those brands, was above all a critic against cartoons which serve a unique purpose : selling to kid, selling to kids, selling to kids**.



*And even if I am very fond of The Simpsons, I totally respect said people.***
**Ok, that's three purposes, but you get the idea.

***Hell, I need such people to listen to my Simpsons quotes all the day, after all.
