A new trailer for It's Always Sunny in Philadelphia season 13 is here. Given the way that the show's last season left off, fans have had quite a few questions about how the Paddy's Pub gang was going to proceed and how that would affect the upcoming batch of episodes. By the looks of things, it's going to be business as usual for Mac (Rob McElhenney), Charlie (Charlie Day), Dee (Kaitlin Olson) and Frank (Danny DeVito). As for Dennis (Glenn Howerton)? It's going to be a very unusual season for him in more ways than one.

The trailer is loaded down with the expected amount of crazy hijinks and ridiculous goings-on that fans have come to expect from the long-running comedy series. We see that Dee and the gang are going to take on the Time's Up movement, in their own unique and quite possibly offensive way. Mac has also gotten into ridiculously good shape and has actually committed to beefing up in a meaningful manner. It also appears as though we're going to get another Wade Boggs drinking record episode with all of the ladies from the show participating this time around. Here's a newly released synopsis for the upcoming season.

"The gang returns, mostly, in the next season of FXX's comedy series It's Always Sunny in Philadelphia. The gang has its hands full as Charlie hopes to have a child, Mac explores his sexuality, Dee takes feminism to new heights, and Frank tries to experience the greatest moment in Philadelphia sports history."

Glenn Howerton doesn't actually appear as Dennis in the new It's Always Sunny in Philadelphia trailer. Though, we do get a pretty disturbing look at how Mac is going to try to fill that void, with Dennis now living in North Dakota raising a family. Mac has created a life-sized adult-friendly doll, shall we say, to emulate his former roommate and best friend. Dennis will be showing up in several episodes this year, but it looks like the show's creative team have come up with some clever and hopefully funny ways to deal with his absence.

The network has already renewed It's Always Sunny in Philadelphia for a season 14. Somewhat surprisingly, that will give it the tie, in terms of season count, for the longest-running live-action American sitcom with The Adventures of Ozzie and Harriet. With the cast all developing more and more projects outside of the series, such as Glenn Howerton's NBC series A.P. Bio and Charlie Day's various movie roles, it wouldn't be too surprising to find out that season 14 will be the show's last, but we won't find that out for some time.
