Homer Is The Incredible Hulk
S13E18 - I Am Furious (Yellow)
Milhouse's father, Kirk, gives a speech to the kids at Springfield Elementary about his occupation of assistant flyer distributor. Due to how boring the speech was, Principal Skinner and Mrs. Krabappel take Lisa's advice and visit the Springfield Writer's Forum to find a better speaker. They find Jeff Jenkins, creator of a popular TV cartoon, Danger Dog. He comes to the school to give a presentation on Danger Dog, including showing them a sneak preview for the next Easter special, and fascinates the kids by telling them about the cartoon industry. Much to Skinner's horror, Jenkins tells the students how easy his job is and how he never needed to work hard to get his job. Later, every kid in school creates their own comic book, all of which are actually rip-off versions of Danger Dog. Bart also creates his own comic Danger Dude (which is actually a dog) and tries to sell it to Comic Book Guy, who criticizes his work. Stan Lee enters Comic Book Guy's store and tells Bart that his comic is bad, but that he should keep trying to "find his own voice."
At home, Bart comes up with a character called Angry Dad, based on the frequent angry outbursts of his father, Homer. Bart rolls out the first issue of Angry Dad, which becomes a hit with the kids in school. During an autograph signing session in the schoolyard, Bart is approached by a spokesman for an Internet entertainment site. He wants to make Angry Dad into an online animated cartoon series, and Bart agrees in exchange for stock. The cartoon becomes an Internet hit, becoming the single most popular non-pornographic website of all time. The only one still unaware of Angry Dad is Homer, who finds out one day at work. Once the humiliated Homer gets home, he finds Bart and strangles him. Marge and Lisa stops him and calms him down, and Homer agrees to suppress his anger from that point on.
The next day, Homer stays true to his word and remains calm. However, his new calm demeanor has taken away Bart's inspiration for his cartoon, so Bart and Milhouse set up a trap for Homer to trigger another outburst. Later, they go to the Internet company office, where they find the company has gone bankrupt. Homer reaches home and happens upon Bart's trap, but he keeps his calm throughout its run, causing lumps to develop on his neck. The trap ends with Homer falling into a pool full of green paint, prompting him to go berserk and storm through town. The police restrain him and Homer is admitted to the hospital. Dr. Hibbert arrives and tells Marge that Bart actually saved Homer's life by enraging him. Hibbert explains the lumps on his neck were actually boils caused by suppressed rage and would have otherwise overwhelmed his system. Homer thanks Bart by taking him fishing, where he continues to make his father angry.
