Halloween's almost here, so we're giving tips on how to dress like your favorite TV characters.

The Costume: The Nightman, The Dayman, Greenman, The Princess Waitress and Charlie's Yellow Proposal Tux from
'It's Always Sunny in Philadelphia'

What You'll Need:
For Nightman – A black karate uniform, a very generous wearing of eyeliner, slicked back hair and some sweet karate moves.

For Dayman – He is the fighter of The Nightman, champion of the sun, a master of karate and friendship for everyone. To convey that, it's all about a gray Spandex jumpsuit with a sash and a dance belt, or, if you want Dayman's bellbottom look, Spandex pants and long-sleeved top. And don't be afraid to expose a little chest hair ... that's how Dayman rolls.

'30 Rock' and 'Mad Men' dominate the Emmys (again), while the show sees its best audience in three years.

I don't really know if it's always sunny in Philadelphia ... never been. But I have been to the set of FX's cult hit 'It's Always Sunny in Philadelphia,' and that was, well, awesome.

Tucked away in a back corner soundstage on the Fox lot in Los Angeles, the 'Sunny' gang hatches their half-baked schemes at Paddy's Pub and hangs out in Charlie's filthy apartment (it's Hollywood, people -- that filth is fake). They also tend to spill show secrets ... if you ask them nicely.

We've got the scoop on September's choice TV-to-DVD releases: We'll let you know when you should dole out your hard-earned dollars, and when a simple addition to your Netflix queue will suffice. -- By Janine LoGelfo

'No. 1 Ladies' Detective Agency' (The Complete First Season) - HBO's series about a strong Botswana woman based on the popular Alexander McCall books has yet to be renewed for a second season -- while that mystery is being solved, familiarize yourself with this gem of a show. Jill Scott's portrayal of the iconic character Mma Ramostwe is like a breath of fresh air, and the show is surprisingly clean for HBO's sensibilities, featuring no profanity, explicit violence or sex throughout the whole season.

Danny DeVito's gone and done it again -- or has he? The actor is denying claims that he was drunk during an interview on a local Philadelphia morning show to promote his raunchy F/X comedy 'It's Always Sunny in Philadelphia.'

While on camera, DeVito repeatedly burped and made lewd comments toward the female reporter who was interviewing him. His bizarre behavior prompted her to ask if he was drunk, since he had just been filming a scene in which he was swigging from a beer can. He claimed there was no real alcohol on the set.

'It's Always Sunny in Philadelphia'
(10PM, FX) 4th season finale
The Paddy's Pub gang is ending the season on a high note ... actually, a musical note, as Charlie's song 'Night Man' -- that disturbing little ditty he penned in season three's 'Sweet Dee Is Dating a Retarded Person' -- becomes a musical.

Dennis, Dee, Mac and Frank help Charlie stage his rock opera, a production which, without recalling all of the tune's lyrics, seems to be about one -- again, disturbing -- thing, but, Charlie insists, is about something altogether dfferent.

We'd love to elaborate more, but this is a family Website. Suffice it to say, it's Charlie and company at their politically incorrect best.

'30 Rock'
(9:30PM, NBC)
It's only the second episode of the season, but Liz Lemon is already facing bigger issues than Tracy and Jenna arguing about the profits of Tracy's pornographic videogame ('Goregasm: The Legend of the Dong-Slayer').

Liz has gotten the dreaded jury duty notice, and she's willing to do nothing less than fly to Chicago to get out of it. But she gets a surprise on the way back when The Big O herself -- guest star Oprah Winfrey, playing Oprah Winfrey -- is sitting next to her on the plane.

Liz sees the chance meeting as her chance to get some of Oprah's self-empowering advice on her life. And Oprah sees Liz as, well, a bit of a whacko.

'30 Rock'
(9:30PM, NBC) 3rd season premiere
If '30 Rock's' second-consecutive Outstanding Comedy Series Emmy brings in new viewers, this episode will be an intro to the show at its best.

Liz Lemon (Outstanding Lead Actress in a Comedy Series Tina Fey) has decided there's room to fill in her life after an 80-hour work week, so she's trying to adopt a baby.

But first, she has to impress adoption agent Bev (guest star Megan Mullally), who stops by the office just as Tracy is celebrating the success of his pornographic video game and Jack (Outstanding Lead Actor in a Comedy Series Alec Baldwin) may have to sleep with Geiss's soap opera addict, Dora underpants-wearing, Mark Wahlberg-lovin' daughter to get his GE job back.

'Celebrity Rehab With Dr. Drew'
(10PM, VH1) 2nd season premiere
He's baaaaack. Yes, Dr. Drew Pinsky, who runs the Pasadena rehab facility where many a D-list star has flocked to get clean, but also one of Dr. Drew's most notorious celeb patients, 'Taxi' star Jeff Conaway.

Conaway, still addicted to pain killers after severe back injuries, is also still reportedly acting erratically (he recently called police and accused Dr. Drew of kidnapping him to rehab).

Meanwhile, other celebs seeking Pinsky's counsel this time around: Police brutality victim Rodney King, 'American Idol' finalist Nikki McKibbin, actress Tawny Kitaen, Rod Stewart offspring Sean and former Guns N' Roses drummer Steven Adler.

'Vice Presidential Debate'
(9PM, ABC, CBS, NBC, Fox)
To quote that great American philosopher Matthew McConaughey, alright, alright, alright.

After weeks of character assassinations and wild accusations being bandied about amongst the candidates, we voters get our first shot at hearing Republican vice-presidential candidate Sarah Palin and her Democratic opponent Joe Biden go head-to-head. PBS political pundit Gwen Ifill hosts the debate, which has already caused the Barack Obama and John McCain camps stress.

Both presidential contenders are reportedly worried that their inexperienced, "gaffe-prone" veep contenders "could commit a momentum-changing misstep in their debate." Sounds like must-see-TV to us.
