Get ready for some raunchy fun.

"It's Always Sunny in Philadelphia" is returning next month, and in the meantime, FXX has released the official trailer. The preview offers a glimpse at the shenanigans The Gang will get up to, and wow, there are a lot. Some of the highlights in the video are the Paddy's Pub employees attending a sexual harassment training, Mac (Rob McElhenney) getting a sex doll that looks just like Dennis (Glenn Howerton), a wild plane ride, and some grabby behavior.

Needless to say, the trailer isn't at all NSFW, but fans wouldn't want it any other way. Watch below.

As you can see, series stars Kaitlin Olson (Dee), Charlie Day (Charlie), and Danny DeVito (Frank) are all back for another season as well, so we can count on The Gang for more fun.

"It's Always Sunny in Philadelphia" Season 13 premieres Wednesday, Sept. 5 at 10 p.m. ET/PT on FXX.
