Simon was constantly ignored. “Springfield Confidential” recalled the exciting days when “The Simpsons” first debuted and the flurry of newspaper articles mentioning its success. Apparently, Simon looked through the reviews, essays, and other reportage and noticed that his name was missing from all of it. Mr. Groening and executive producer James L. Brooks were mentioned, but Mr. Simon began to feel like they were “different people.”
Simon has previously worked on hit shows such as “Cheers” and “Taxi,” and he also assembled and led the writers’ room on “The Simpsons.” Nevertheless, Gröning was cited as the sole driving force behind the show. It was Groening who was interviewed by industry insiders and who was invited to speak on “The Tonight Show.” surely, When Groening visited “The Tonight Show” On September 26, 1991, cartoonists aimed to give credit where credit was due and name all of the greatest members of the “Simpsons” team during the broadcast. Sadly, Jay Leno kept cutting him off. For Leno, the more interesting story wasn’t that a dedicated team of hard-working, old-school professionals created a great show, but that one underground comic artist single-handedly disrupted entire pop culture. It seems that.
Mike Reese estimates that the constant admiration for Gröning and the lack of credit he received infuriated Simon. Rhys likened him to Salieri from Amadeus, and was furious that a “young upstart” was taking over the world while the genius was still buried in obscurity. Eventually, Simon began to treat Gröning roughly in the office, glaring at him and making snide remarks at his expense.
It’s no surprise that Simon pitched the idea for “Flaming Moe’s.” This story is about one person, Mo, receiving all of the efforts of another person, Homer.
