A recent episode of It’s Always Sunny referenced a real-life, horrific skiing injury

“The Gang Hits The Slopes,” a recent episode of FXX’s It’s Always Sunny In Philadelphia, is mostly an homage to the party-hearty ski comedies of the 1990s, even going so far as to score a prominent guest role from actor Dean Cameron, star of those T&A-heavy VHS classics Ski School and Ski School 2. But its gruesome ending, a climactic skiing competition between Dennis and Charlie, is actually drawn from real life. Thinking that they’re racing for the fate of an entire mountain, the two men invest themselves heavily into a supposedly all-or-nothing downhill race, even though Dennis is an accomplished and experienced skier, while Charlie is a clumsy novice. All seems to be going great for typically overconfident Dennis until he can’t resist showing off a little and manages to loudly shatter both ankles in a pointless display of skill. He’s so determined to win that he painfully drags his mangled body across the finish line, all while screaming about how his ankles are broken. This incident, however, is no screenwriter’s invention; it is drawn from an actual incident involving professional skier Tanner Hall, as documented in ESPN’s coverage of the X Games. The dialogue in the Sunny episode is ported over almost word-for-word from reality.
