Every season of FXX’s You’re The Worst is a four-way race to the bottom, as Jimmy, Gretchen, Edgar and Lindsay all compete to see who can most thoroughly screw up their own lives in the most drastically funny ways. The show’s third season ended on one hell of a downer note, though, with Jimmy leaving Gretchen directly after she said yes to marrying him, and so the trailer for the show’s upcoming hour-long fourth season premiere suggests things will be even more awful than usual. Between Gretchen declaring “mushroom cloud, bitch” and hunting around for crack, and Jimmy getting his ass kicked by retirees, it seems safe to say that the show will continue to plumb the depths of rock bottom when it returns on September 6.
