Mac, Dennis, Charlie, Dee, and Frank are all at it again for season 11 of It’s Always Sunny in Philadelphia.

What are we exactly referring to by “it”?

Well, by now, you should know that it is whatever the worst thing is, it is the gang trying to one up that. 

See for yourself in this upcoming season’s teaser, then look for the season premiere on Wed. Jan. 6th on FXx.
