The last season of It's Always Sunny In Philadelphia ended on a bit of a downer as Dennis announced that he was leaving the gang to be with his secret family in North Dakota.

The real reason that Dennis was leaving the show was Glenn Howerton, who plays Dennis, got a new gig on a show called A.P. Bio.

Earlier this year, it was rumored that Dennis might be back, or at least might make some appearances in the new season.

The last episode of It's Always Sunny aired back in March of 2017. Fans of the show have been awaiting it's triumphant return ever since. Well, a year and a half later, it's finally happening. The new season will premier on Wednesday, September 5th.

Since the show last aired, Mac decided to get super ripped, which is the complete opposite of when he got fat. Here's the trailer for the new season with Dennis (sort of) being back.
