It’s hard to gauge which of the gang’s many business failures was the worst, but they’ve certainly had major failures more than once. Their first semi-official attempt at a job came in season 3, “The Aluminum Monster vs. Fatty Magoo,” when the entire gang tried to start a women’s clothing factory and eventually got dozens of dresses they couldn’t sell. There were many plans before that, but Frank didn’t have the capital to start them. So what about other initiatives? Mac and Charlie’s “Fight Milk” drink made with real crows makes people violently sick And several UFC fighters were fired. Charlie’s soundproofing Kitten Gloves may have made him money, but he accidentally sold the rights to a lawyer. The door-to-door petrol business of the guys in “The Gang Solves the Gas Crisis” was a huge fiasco, their attempts to commodify Paddy’s often end in felony offenses and they fail at anything. So why do fans keep rewatching to see how they fail again and again?
It goes without saying but the gang are horrible people. Seeing them succeed makes “It’s Always Sunny In Philadelphia” a very different show. One of the things that makes them cute is that they can’t win, which makes it a little easier to identify with them. It’s also hilarious to see horrible people suffer the consequences of their actions. Just as “Succession” is a tragedy about terrible people who have everything and still can’t win.“It’s Always Sunny” is a comedy about horrible people who have nothing and can’t win. The important thing is that they didn’t win.
