It's Always Sunny in Philadelphia - Season 17

Season 17

In the latest season, "The Gang Embraces The Corporate Era:" The story of how greed and the New American Dream have consumed Paddy's Pub.

Seventeen seasons on, Ronald "Mac" MacDonald, Charlie Kelly, Dennis Reynolds, Dee Reynolds, and Frank Reynolds return to shamelessly shed their "niche" label for grander aspirations.

They'll exploit cross-network promotion to increase market share; they'll scapegoat one of their own to avoid a PR backlash; they'll risk everything for a handshake with the Saudis; they'll bend the laws with side hustles to pad their pockets; and they'll change everything about themselves to appeal to a broader audience.

And sure, like any corporate goon, the Gang craves money and parasitic social privileges. That's been plain since 2005. But they're also human beings. They crave love.. respect... conditional freedom... constant adulation... histrionic amounts of attention... non-stop gratification... and unfiltered, slaphappy eroticism.

In Season 17, they'll chase down them all.

And the money. Obviously, the money. They don't want to spend the rest of their lives working like dogs.
