It’s Always Sunny in Philadelphia returns for Season 18, Episode 8 tonight, Sept. 28, on FXX and Hulu. The Gang has had a busy season so far, waging war on non-alcoholic beer, visiting the Renaissance faire, getting tested for neurological disorders, discussing conspiracies, and going to college. It’s basically an average day in the life of Charlie Kelly, Dennis Reynolds, Ronald “Mac” McDonald, Deandra “Dee” Reynolds, and Frank Reynolds.
Episode Title Gives a Hint
The title of Episode 8 is “Mac and Dennis Tear Their ACLs.” That suggests a physical comedy disaster, and given the show’s history, it’s probably not the kind of injury that gets fixed with a brace and a week off. The episode drops at 9 p.m. ET tonight on both platforms.

You can watch new episodes of It’s Always Sunny on Hulu, which streams every episode of the series. New episodes drop on Mondays at 9 p.m. ET. A Hulu subscription costs $11.99 per month with ads, or $18.99 per month without ads.

What Happens Tonight
The episode title focuses on Mac and Dennis, though the gang’s adventures tend to involve everyone eventually. Expect chaos, misunderstandings, and the kind of disaster that defines the show’s brand of humor.
The Season So Far

Our View on the Title
The title is a good hint, and the gang’s adventures this season have been a mix of absurdity and chaos. A war on non-alcoholic beer, Renaissance faire hijinks, neurological disorder testing, conspiracy talk, and a trip to college — it’s all par for the course. The show has spent years proving that the gang’s worst ideas are often the funniest ones.
The episode title promises more of the same chaotic nonsense. It’s Always Sunny in Philadelphia continues to deliver on its promise of absurdity, and tonight’s episode looks like it will follow that pattern.
