"Why Do Fools Fall in Lava?" is an episode of The Itchy & Scratchy Show. It was a very low rated cartoon and inspired the creators of the show to seek help in improving it.
Scratchy pays Itchy for a bungee jump in the volcano, and Itchy cuts open Scratchy's belly and ties his intestines. Then he shoves him into the volcano, and as soon as he is about to plunge in the lava, the intestines hold on. As Scratchy sighs with relief, Itchy fills his intestines with gasoline. Scratchy tries to hold the gasoline inside but he bursts and is reduced to cinders by the lava.
