Season 9 of It's Always Sunny in Philadelphia will debut on Wednesday, Sept. 4 at 10/9c. The League's fifth season premiere will follow at 10:30/9:30c. Totally Biased kicks off its five-night-a-week run that Wednesday at 11/10c.

FXX orders first original series from Archer creators

At their Comic-Con panel on Sunday, moderated by TV Guide Magazine's Damian Holbrook, It's Always Sunny's cast and creative team teased an upcoming Lethal Weapon 6 episode and revealed new details about the episode written by Game of Thrones showrunners D.B. Weiss and David Benioff, called "Flowers for Charlie." "It's kind of like Limitless where I'm talking a pill to be more smarter," Charlie Day said.

Launching on Monday, Sept. 2 at 7 a.m., FXX will air new episodes of several of FX's beloved original comedies, as well as repeats of hilarious classics such as Freaks and Geeks and Sports Night.
