Hidden Messages In It's Always Sunny In Philadelphia You May Not Have Caught Onto

The FX sitcom "It's Always Sunny in Philadelphia" continues running strong since it premiered in 2005–in 2020, FX renewed it for four more seasons, which will bring the show up to 18 seasons in total (via The Hollywood Reporter).

Given how cheap the show's pilot was to produce, and given the show's subject matter, it might seem like "It's Always Sunny" is thrown together. That's not the case. The creators put plenty of care and attention to detail into each episode. Some jokes are so well-hidden you might not spot them.

If you're a fan of the show, you might have noticed something strange about the end credits. After the credits have rolled, there's a production bumper for stars Rob McElhenney, Charlie Day, and Glenn Howerton's production company, RCG Productions (formerly RCH Productions). The bumper has a quick voiceover of what sounds like gibberish, but is in fact a message played backwards. For most seasons of "It's Always Sunny in Philadelphia," Howerton, McElhenney, and Charlie Day recorded a new message for their RCG production bumper, but sometimes they recorded unique ones for certain episodes.

Without further ado, here's the list of messages, season by season.

Season 1  

McElhenney, Day, and Howerton: "You're stupid for playing this forward."

Season 14

McElhenney: "They leave, but they all come back. Brown."

Season 15

All three, singing: "Four walls, the better brown" (via It's Always Sunny Wiki).

Why all the "browns?" Most likely that's a reference to the Philadephia-area band Ween, of which the trio are big fans–Ween uses the word "brown" as slang for "cool" (via Swim into the Sound). As for "Four Walls," that's a reference to the trio's recently released whiskey (via The Hollywood Reporter).
