Season 7 kicks off on September 15 (10PM ET, FX), and in these cheeky new promos for It’s Always Sunny in Philadelphia, we see that star Rob McElhenney‘s intentional 50-pound weight gain is indeed one of the storylines.

The second clip, spoofing The Miracle Worker, revolves around Charlie Day‘s Charlie and Danny DeVito‘s Frank, whose on-screen chemistry is one of the best things about the show.

Season 7 promises to be another great addition to the Sunny history, as Charlie Day told me earlier this year that season 7 storylines will include a poke at Facebook, Frank’s reunion with his brother (the two became estranged after fighting about a woman) and a spoof of kiddie beauty pageants.
