The goal in a show is to remain true to its own brand of humor.
And Rarely do shows continue to push the envelope without jumping the shark, but "It's Always Sunny in Philadelphia" proves to be the exception.
In the newly released teaser, the 7th season-- which includes vomiting, hookers and beauty pageants--looks just as zany, morally reprehensible and borderline gross as ever.
The cast also schools us in its inventive language: "assd-ck" and "d-ckhole" and "white stains."
It just makes you wonder: What will they think of next?
