It’s Always Sunny in Philadelphia: “Flowers For Charlie” (Episode 9.08)

Can a simple pill turn an idiot into a genius? That’s the premise of Flowers for Algernon, the 1966 epistolary novel by Daniel Keyes, and now it’s also the premise of “Flowers for Charlie,” the slightly less ambitious (but way funnier) eighth episode of It’s Always Sunny’s off-and-on ninth season, written by Game of Thrones creators D.B. Weiss and David Benioff.
It starts in a lab, where the gang is clamoring to be included in an “intelligence experiment” that pays $1,000. The two scientists, though, only want a single subject, and they want him to be as dumb as possible. Dee offers to have sex with both of them, but they’re not enticed. Instead, they set their eyes on Charlie, who proves that he’s no smarter than a lab rat when he repeatedly shocks himself reaching for cheese. The scientists (played by The Dark Knight Rise’s Burn Gorman and 2 Broke Girls’ Jimmy Ouyang in the best supporting turns of the season so far) are delighted; they’ve got their man.
Charlie takes a pill, and immediately begins to show signs of intelligence. He teaches himself Mandarin using an audio book (“I just realized I have two ears,” he tells Dennis), and refuses to kill a giant rat Dee finds in the bar. That means it’s up to the rest of the gang, and they use the opportunity to demonstrate their wit. Mac’s strategy is to bash the rat with a baseball bat wrapped in chains, but Dennis sees the process as a seduction and takes a more cerebral approach. He puts on romanitc music (“You’re The Inspiration” by Chicago) and baits a glue trap with brie cheese. For a weird moment, Mac looks like he’s trying to kiss Dennis, but soon Dee enters with an even better idea—she’s got an “ultrasonic rodent repellent” device, and she plans to obliterate the rat’s ear drums. All three put their plans in motion, and when Dee sticks her hand in the wall to set the repellent, her hand gets stuck in Dennis’ glue trap as the rat escapes.
Meanwhile, Charlie’s brain power seemingly keeps increasing. He plays chess with one of the scientists and posits that Stephen Hawking is “more Lady Gaga than Johann Sebastian Bach,” and rejects Frank when he wants to watch a Police Academy movie as part of “Gruesome Twosome Tuesday.” Instead, he continues to read and devise mathematical formulas and win at chess. Frank grows desperate, and pays the waitress $500 to have lunch with Charlie in an attempt to bring him back to earth. As he tells the rest of the gang, Charlie is their foundation, and the foundation belongs on the bottom. But Charlie is alarmed by the waitress’ stupidity, and begins to experience more side effects of the pill, including sharp pains in his head and complete numbness of the legs.
