There is something about FX's comedy series It's Always Sunny in Philadelphia that is just plain wrong — in a good way.

The show is produced by, and stars Rob McElhenney, Charlie Day, and Glenn Howerton, as Mac, Charlie, and Dennis, respectively. These three are ne'er-do-well friends who co-own a bar and constantly find themselves in trouble of their own creation. Along for the ride, as co-owners of the bar, and causing trouble themselves are Dennis's sister, Dee (Kaitlin Olson), and father, but not biologically, to Dennis and Dee, and maybe, biologically, Charlie too, is Frank (Danny DeVito).

Just reading that last sentence ought to provide one with a pretty good idea about the show. It is a comedy where absolutely nothing, except common sense and moderation, is taboo.

The first episode of season 3, premiering Thursday September 13 at 10pm, is entitled "The Gang Finds a Dumpster Baby." Predictably here, the gang hears some crying coming from a dumpster and finds a discarded child. Rather than give the child to the authorities and have the child get lost in the "system," they bring the baby back to the bar, and Dee and Mac decide to raise it.

The two eventually get the idea that the baby could become a child star and begin shopping it around to talent agencies only to find that the child is not ethnic enough. Not to worry though, Dee and Mac have a plan to fix this. The rest of the group is involved in various other shenanigans during the show, from pretending to be an environmentalist in order to avenge an insult, to turning into overly enthusiastic recyclers that sleep on the street.

DeVito was added to the show in its second season, and while the character fits in persona-wise with the other wretches on the show, it does smack of stunt-casting and feels rather forced. The four younger members of the gang do not seem the type to hang out with any father, no matter whose father he may or may not be. Even so, DeVito is game and appears not to mind the utter lunacy that his character continually spews.
