"It's Always Sunny In Philadelphia" To Do 4th Season | Sharapova's Thigh

Entertainment Weekly:
"The half-hour show, about four friends and the Irish dive bar they operate when not getting into unwholesome trouble, is scheduled for a 13-episode run. An air date has not yet been determined, but the writing staff is already sketching out story ideas with production tentatively set to begin in June. The main cast will return in its entirety, including Danny DeVito as the gang's twisted father figure."
I just got into this show when I received seasons 1 and 2 on dvd over the holidays(thanks sis), and I fucking love it. It immediately became one of my favorite shows. If you like drinking, and shows like "Seinfeld", "Curb Your Enthusiasm", or "The Office"... you'll love this show. It goes places that most shows don't have the stones to go(like "Curb"), and that's why it kicks ass in my opinion. Of course, if you get offended easily, then I'll tell you right now it's not the show for you. This is from the Wikipedia page of "Sunny":
"The series deals with a variety of controversial topics, including abortion, gun control, physical disabilities, racism, sexism, religion, the Israeli/Palestinian situation, terrorism, transsexuality, slavery, incest, sexual harassment in education, the homeless, statutory rape, drug addiction, pedophilia, child abuse, mental illness, gay rights and prostitution."
Unfortunately season 3 happened before I started watching the show, so hopefully they'll have the re-runs on FX very soon.

UPDATE:
You can watch seasons 1 and 3 here!
