In the premiere episode of FX's raunchy sitcom It's Always Sunny in Philadelphia, the viewer is introduced to Paddy's Irish Pub co-owners Mac (Rob McElhenney), Charlie (Charlie Day), Dennis (Glenn Hoowerton), and Dennis' sister Dee (Kaitlin Olson). Lately, the business at Paddy's hasn't been so good, and the gang is eager to bring in some new clientele. Realizing that the best way of increasing their profile is to advertise, the owners of Paddy's agree to hire Dee's acting friend Terrell as their new spokesman. Later, after Charlie and Mac make some insensitive remarks that smack of racism, the pair launches a concerted effort to prove that they aren't prejudice. ~ Jason Buchanan, Rovi
