'It's Always Sunny in Philadelphia' is back for a seventh season (premieres Thurs., Sept. 15, 10PM ET on FX), and judging by what the cast revealed when I visited the set, the gang is all in fine 'Sunny' form.

"This is like, without a doubt, the craziest season," Danny DeVito said. "Danny brought it all in," Rob McElhenney noted. "And he's devolved over the last few years on a personal level, and so we've taken advantage of that and put that in the show."

The season premiere features their version of 'Pretty Woman,' which is much more grounded in reality. "Julia Roberts would only look like Julia Roberts for a very short period of time on the streets before looking like Julio Roberts," Glenn Howerton said. Charlie Day chimed in, "Someone would've cut that b*tch!"

Then there's a 'Toddlers & Tiaras'-inspired kids beauty pageant that the cast had a lot of fun with. "It's one of my favorites," Kaitlin Olson admitted. "Dee's really into it, which is always so fun for me, when she's super into something." "Put a five year old in some WOW! Wear, and it just says America," Day added.

If you're a fan of FX's delightfully irreverent comedy 'It's Always Sunny in Philadelphia' -- the funniest show on TV, IMHO -- you probably already know the basics: The show was the brainchild of actor pals Rob McElhenney, Charlie Day and Glenn Howerton, who spent around $100 on tapes and shot a DIY pilot that was later bought by FX.

Now that we've all been entertained by the screenwriting talents of Charlie and Mac, witnessed Dennis and Dee explore the worst parts of dating with the D.E.N.N.I.S. System and seen Frank's naked body, what's next for the 'It's Always Sunny in Philadelphia' gang?

Two words: Tom Sizemore.

I caught up with Glenn Howerton, Danny DeVito, Kaitlin Olson and Rob McElhenney to find out about the new season (premieres Thurs., Sept. 16, 10PM ET on FX) and got an earful about Hollywood bad boy Sizemore and his awesomely twisted turn on the show.

We also talked babies (Olson and McElhenney are expecting their first child, a girl, any day now) and, of course, the best ways to get them tanned and camera-ready (see "The Gang Finds a Dumpster Baby" if you don't get the joke). Then we touched on what's got DeVito's balls on fire, how many more seasons the show will go and why we do or don't -- there are conflicting opinions on this -- want to see a 50-year-old Sweet Dee.

(S05E12) Well, that's it for season five of It's Always Sunny in Philadelphia. It would have been foolish to expect something mind-blowing this week, because, as usual, the show didn't go out with a bang or any nail-biting cliffhanger. Instead, there were people vomiting, naked chicks in blacklight paint, beer, and lots of screaming. Just another day for the owners of Paddy's Pub.

(S05E11) I think we all need to take a hot second to review what fantastic, life-improving ideas this season has presented us thus far. Earlier, we learned the benefits of funneling box wine into soda cans (beyond the immediate high class appeal of it all). Then we were schooled in the ways of the DENNIS System, allowing us to more efficiently get ladies to bang. And in this episode, we learned that keeping sausage links in your shirt pocket is a smart way to keep your hands free and open to get greasy in other ways.

This is all shaping up to be a fine education, folks. I think it goes without saying that It's Always Sunny in Philadelphia is Sesame Street for adults.

(S05E10) A weird thing has been happening this season, where I find myself really appreciating what the writers have been doing with the gang but I'm not laughing nearly as much as I should. This episode was a prime example of that. Dennis is notorious for his way with women, so hearing a full breakdown of the DENNIS System should have been a complete riot (a riot with cringing, sure). I smiled at certain parts and quietly enjoyed the scary-elaborate ways of Dennis and the rest of the gang, though ultimately, the laughs fell short. Perhaps things are feeling a little forced this season?

Trust in the douchiness of your characters and the chemistry of your actors, writers! The lines will come.

(S05E09) Well. This episode was certainly successful in further quelling the doubts of any audience members that are still, for whatever reason, unconvinced that all the guys from It's Always Sunny In Philadelphia are actually super-gay for each other. Yeah, not just "gay" but "super-gay." Considering the adorable, almost symbiotic nature of the guys' relationships, I would probably just refer to them as "hetero lifemates," but Frank and Charlie play Nightcrawlers and we all know what happened onstage between Dayman and Nightman in "The Nightman Cometh." Don't fight it.

(S05E08) Yes! Finally. The moment we've all been waiting for. Ever since the season five promos first aired, I have been eagerly anticipating some sort of context for Charlie's uncontrollable eyebrows and the ridiculous Kitten Mittens (or Kitten Mittons, as it were). Seeing the ad in full certainly didn't disappoint, though I wish we could have seen more Kitten Mittons throughout the episode. Admittedly, thirty-some minutes of cats struggling in booties probably doesn't sound like a hot idea, but, hey, animal humor has sustained many a clip show.

Plus, I heart over-enthusiastic Charlie.

(S05E07) This episode brought back many things that fans of It's Always Sunny In Philadelphia have already come to know and love: nearly aggressive patriotism, needless shirtnessness, songs sung in falsetto and, of course, Rickety Cricket. I would like to also submit that the Birds of War get-up (pictured above) would be perfect for this Halloween, especially if you're desperate for few high-fives or silent nods of approval. It covers a wide range, as it appeals to both Always Sunny fans and people who like America and/or chickens. I mean, eagles.

(S05E06) Ooh! Things I learned in high school! This episode of It's Always Sunny In Philadelphia was presented as a frame story, just like The Canterbury Tales. Did the gang out-Chaucer Chaucer!? Well, no, but it was a lot funnier than the Wife of Bath, I can promise you that.

There were a lot of excellent moments (read on to find out who won the "Best Retch-Face" award, which is as coveted as it is imaginary) and they made for a solid episode, though not one to immediately jump into my favorites. Admittedly, that's an unreasonable weekly expectation anyway. Oh well. At least we got some Greenman.

This was bound to happen, wasn't it?

In a TV first, a sitcom from a basic cable network has been syndicated on another basic cable network: Comedy Central has nabbed the rights to FX's It's Always Sunny in Philadelphia.

According to the press release, the gang from Paddy's Pub will make an appearance for the first time on Comedy Central for a limited run next summer with the long-term license window starting after the first of the year in 2011.

(S05E05) This, more than any of the other episodes from the current season, felt the most true to the show. I know, that's kind of weird, since the canon is growing and developing with every installment, but this episode had all the things that we've come to know and love from It's Always Sunny In Philadelphia, from Frank's increasingly speedy spiral toward rock-bottom to Charlie and Dee's personal issues with the Waitress (never give her a name, for the love of everything that is terrible and in poor form). The schemes and the chemistry of the gang was extra-perfect in this episode, especially during the rapid-fire conversations surrounding Mac, Dennis and Charlie.

This is one of those episodes I've pocketed away in case I need to subject -- I mean, introduce -- an uninitiated person to the world of Always Sunny.

(S05E04) This week didn't really bring anything mind-blowing, but it returned us to old stomping grounds. With this episode, It's Always Sunny In Philadelphia revisited a few familiar themes: gross people from the gang's history and the never-ending quest to bang moms. Mary Lynn Rajskub (remember, it's like "rice cub") made her Always Sunny debut as Dee and Dennis' "garbage pail cousin," Gail the Snail, and successfully joined the McPoyle brothers in that elite league of characters that make viewers feel greasy just from looking at them too long.

(S05E03) Something was a little off about this episode. I still can't tell what triggered this reaction. I think it was because I only half-laughed once or twice during the entire thing, or perhaps it was the heavy-handed product placements that were too involved to be casual and excusable. Certainly, it wasn't terrible television; it just didn't live up to the quality that I've come to expect from the show.

If I wanted to be harsh and really ballsy, I could say this was one of the weaker episodes from the series. But I won't. Because I have no balls (I haven't perfected the technology for me to engineer a pair).

(S05E02) Although it's interesting to see the individual characters play in their own storylines and schemes every once in a while, there's a lot to be said about the chemistry and rapid-fire interactions when all five members of the gang are stuck together for an entire episode. Doubly so when it's an episode that mainly takes place in a tiny car or cramped U-Haul.

In addition to this, their poor decision-making seems to escalate faster when they're feeding off each other's bad intentions, which means more laughter and delighted points-at-the-screen for us bozos.
