When a cartoon animator speaks to Bart's class on career day, Bart gets the idea to make an animated series of his own. After countless efforts and derogatory statements from Comic Book Guy, Bart's attempts at cartooning come to a crashing halt. That is until the biggest character of all inspires him at home: Homer. Bart creates a character based on Homer called "Angry Dad," that chronicles Homer's daily antics via flash animation on the Internet.
Bart's problem however, is that he's running out of material when Homer begins to suppress his rage. As a result, Bart decides to create an elaborate scheme to make Homer go crazy and provide ample fodder for his cartoon. When Homer falls victim to Bart's prank, he becomes so enraged that he turns into a delirious version of the Incredible Hulk and has to be subdued by countless police officers from Springfield's finest. In the end, Homer realizes that keeping all the rage inside can sometimes actually be a bad thing.
