The Lesion of Super Heroes

The Lesion of Super Heroes is an Itchy & Scratchy comic. When Bart, Milhouse, and Martin snuck into the company who publishes the Radioactive Man comics, they got a sneak peek at this.

Plot
A superhero cat is inducting Scratchy into his superhero squadron. Scratchy thinks it's an honor to be in a club where all the members have at least one super power. The super cat tells Scratchy his power is that he can turn into any superhero he wants, revealing himself to be Itchy in the process. Itchy then turns himself into a Wolverine-esque superhero, and slashes Scratchy to bits.

Reception
Bart and Milhouse enjoyed the strip and hoped that someday, they'd animate it and air it on The Krusty the Clown Show. Martin, however, was more worrying about getting caught than having fun and enjoying the comic.
