After six seasons of "It's Always Sunny in Philadelphia," you probably thought "the Gang" had reached the bottom of the barrel. But as the following clips demonstrate, season seven will see Mac, Dee, Dennis and Frank sink to filthy new lows.

A lot has been made of Mac's 50-pound weight gain and Frank getting married to a prostitute. But up until now, I haven't heard much about Dee's gratuitous use of the term "white stain," or Dennis' fondness for bringing up "balls to the chin." Well, these new clips shed some light on those subjects. You're welcome.

Season seven begins Thursday, September 15th at 10:00 ET/PT on FX.
