AP Photo, FX, Patrick McElhenney SAN DIEGO (AP) - "It's Always Sunny in Philadelphia" has plenty to be thankful for: The naughty FX comedy is going into its ninth season, helping to launch a new spin-off channel and was greeted by more than 5,000 fans at the show's Comic-Con panel Sunday in Hall H at the San Diego Convention Center. "Always Sunny" cast members Rob McElhenney, Glenn Howerton, Charlie Day, Kaitlin Olson and Danny DeVito were on hand to answer fans' questions after screening the first episode of the new season, which is debuting on the FX spin-off network FXX in September. Howerton said the new season will include episodes featuring Thanksgiving, "Lethal Weapon 6," a flu epidemic and an installment written by "Game of Thrones" co-creators David Benioff and D.B. Weiss titled "Flowers for Charlie." "It's kind of like 'Limitless,' where I'm taking a pill to be more smarter," said Day, who plays the goofball character. One thing fans won't see is the dysfunctional gang from Paddy's Pub going on "Family Feud." McElhenney said the network vetoed an episode written for the upcoming season featuring the character going on the game show. He said "Family Feud" was on board with the idea, but it didn't come together.
