After Frank, Dee and Dennis found unique ways of dealing the passing away of Mac and Charlie, who faked their deaths to save their lives from Mac's revenge-obsessed father, the gang returns tonight to find out “Who Pooped the Bed?”

Read on for a preview of tonight's episode of It's Always Sunny in Philadelphia.

The seventh episode of the fourth season is all about feces.  Frank and Charlie discover that someone has soiled their bed so Mac and Dennis join them as they attempt to find the culprit.

The episode also features the return of Artemis (Artemis Pebdani), Dee's friend from her acting class.  Previously, she appeared in the episode "Charlie Has Cancer" in which she was hired to work at the bar in attempt to make it more like a Coyote Ugly Saloon.  She also appeared in "Charlie Goes America All Over Everybody's Ass," where she showcased her fondness for performing in the nude, as well as in "The Gang Gets Invincible," where she watched and made fun of Frank while he was in the toilet.

In “Who Pooped the Bed?” Dee leads Artemis and the waitress on a fun night on the town, Sex and the City-style.

It's Always Sunny in Philadelphia stars Charlie Day as Charlie, Danny DeVito as Frank, Glenn Howerton as Dennis, Kaitlin Olson as Dee and Rob McElhenney as Mac.
