I initially confused It's Always Sunny in Philadelphia with Sonny With a Chance which is a Disney kids show and not at all like the very not-kids It's Always Sunny. OK, I can't believe I just admitted that. It's pretty embarrassing. The only similarity is the word sunny and even that's spelled different. I mean, look:
Moving on, It's Sunny is a little difficult to explain since the premise is so basic. A group of friends in Philadelphia run an Irish bar, hilarity ensues. You could say it's Cheers for the slacker generation, since none of these guys have their lives together and are overall a hot mess of immaturity and ineptitude. Often hilarious, sometimes irritatingly so, this show is pretty wacky, but later episodes solidify into a groove. You can catch this as new episodes air on FX, or reruns on Comedy Central and I hear WGN is running them now, too.
Why You Should Watch: I got my first glimpse of the show from a clip that went viral online with a cat in wearing "kitten mittens" to keep it from being so loud (cats + internet = success!) If your humor trends that way, you will like this show.
Factoid: The pilot episode is rumored to have cost only a few hundred bucks - or less - because it was filmed by handheld camera with all the actors working for free. Danny Devito was added to the cast in season 2 - and there's your Cheers connection!
