After a 10-month break, the gang is back and up to its old tricks.

The fourth season of “It’s Always Sunny in Philadelphia” premiered Thursday with two new episodes that were as twisted, absurd and hilarious as any before them.

For those unfamiliar with the show, “Sunny” can best be described as “Seinfeld” for the 21st century. The self-centered characters get into bizarre situations that usually are grounded in some sort of current event, but then are quickly taken to some extreme which always end up backfiring.

In “Mac and Dennis: Manhunters,” the Gang — Mac, Dennis, Charlie, Dee and Frank — are interested in finding people. Mac and Dennis want to find someone to hunt while Charlie and Dee want to find someone to eat. Frank weaves between both storylines as the provider of the human flesh that caused Charlie and Dee to be stricken with “the hunger” and as a helper to the man Mac and Dennis are hunting.

There are also a large number of “First Blood” references, due to the fact that Frank keeps confusing his life with John Rambo’s.

The second episode, “The Gang Solves the Gas Crisis,” finds the group defining where they fit in with relation to the Gang. Each is defined as the Brains, the Looks, the Muscle, the Wild Card and the Useless Girl. With their roles properly defined, like the A-Team or the Ghostbusters, the Gang devises a plan to hoard gasoline and sell it months down the road.

There is also a nice subplot that throws terrorism into the mix and wraps everything together nicely.

Much like “Seinfeld,” the show doesn’t provide lessons.

The difference lies in the topics, as you can tell by some previous episode titles: “Charlie Wants an Abortion,” “Charlie Got Molested,” “The Gang Goes Jihad” and “The Gang Finds a Dumpster Baby.”

The center of the show lies in its “nothing is taboo” mindset. The Gang has pretended to be disabled, terrorists and decent human beings in order to get ahead.

Despite its constant ridiculousness, “Sunny” does provide social commentary.

During “The Gang Solves the Gas Crisis,” Frank waterboards Dee. When asked if it works, Frank said yes because she confessed to doing things she never did.

Steroids are tackled in “Hundred Dollar Baby,” as is underage drinking in “Underage Drinking: A National Concern” or gun control in “Gun Fever.”

Those who are unfamiliar with the series may miss an occasional reference to a previous episode, but because the show does not have one storyline, newcomers will find “Sunny” as great as hardcore fans.

And for the people wanting to catch up, the first three seasons are available on DVD.

With the season just beginning, there is no doubt “Sunny” is going to bring the funny by not only pushing the envelope, but by setting it on fire. Tune in at 9 p.m. Thursday nights on FX.
