When it comes to plotting, planning, conniving, and going over the top for personal gain, there is perhaps no better master schemer in all of television history than Frank Reynolds. As one of the central characters on It's Always Sunny in Philadelphia, Frank has gotten himself into many sticky situations. But in the vast majority of them, he only has himself to blame. He funds many of the gang's operations and drives them to do more outlandish and expensive things.
It's hard to say what has truly driven Frank to any of the show's extreme scenarios. It could be his childhood struggle with "donkey brains" and Froggy, or just a penchant for doing the most bizarre, most outrageous things imaginable. After all, he claims to embrace his self-described wildness to a greater extent than any of the other characters. Of all the motley group of weirdos in one of the best shows to binge watch, Frank is definitely a standout for his many wild schemes.
In "Thunder Gun Express," the gang is excited to see the biggest movie of the summer, but there's just one problem: the president is visiting the city, and traffic is a nightmare. Though he is left behind for running too slowly, Frank takes control of a tour boat filled with tourists to get to the movie theater. Still expecting a tour, his passengers ask him to talk about the city, so he recounts stories from previous episodes. But when he docks the boat, the police are already waiting to detain him.
He's allowed his one phone call, so Frank calls the theater where the rest of the group is getting prepared to watch the movie and reports an incendiary device is inside.
In "Charlie Goes America All Over Everybody's A**," Frank, Dennis, and Mac transform Paddy's into an "anything goes" bar. While Dennis and Mac do this to bring in more people and encourage women to take off their tops on camera, Frank wants to set up a no-rules gambling ring. Dennis and Mac, unhappy about Frank's concept of freedom, agree that he should be given the basement while they take the bar. Throughout the episode, Frank's setup degenerates from a card game in the main bar to a game of Russian roulette reminiscent of The Deer Hunter in the basement.
Their experiment in freedom ends when Dennis decides to call the cops because a man shoots himself in the head.
The episode "Dennis and Dee's Mom Is Dead" includes an abundance of shenanigans, even by It's Always Sunny standards. After the passing of Frank's ex-wife and Dennis and Dee's mother, Barbara, it is revealed in her will that she did not leave any of her money to Frank or the kids, but instead gave it all to her lover, Bruce Mathis. To get back at Barbara and get the money he thinks he rightfully deserves, Frank attempts to extort money from Bruce by posing as Dee's fiancé. Bruce, aware Frank is Dee's father, strings them along by offering children for them to adopt and trying to make them sleep together. Bruce only reveals he knows of the scam when they're at the altar preparing to get married.
When Frank and Dee exchange their vows, Bruce admits he knows that they're father and daughter, and they receive nothing.
Throughout the series, Frank mentions his company, Wolf Cola, in passing. And though it begins as a means of tax fraud, the company takes on a life of its own. First mentioned in "Sweet Dee Gets Audited" as an off-shore shell company, it becomes increasingly legitimate in order for Frank to avoid an audit. He turns a eulogy for a fake baby into a Wolf Cola advertisement and tries to encourage cult members to buy his soda. But it is in the episode "Wolf Cola: A Public Relations Nightmare" that Frank encounters an image blunder of the highest order.
Wolf Cola becomes the official soda of the extremist group Boko Haram. Initially happy because he thinks it's the preferred drink of "the Jews in Boca Raton," he tries to find a way to fix the PR nightmare. Ultimately, Frank doesn't need to do anything to fix the problem because the scandal dissipates due to the 24-hour news cycle and a UFC doping scandal caused by a product distributed by another one of Frank's companies, Fight Milk.
