You know that lady on 'Party Down' with short hair and pink glasses that just seems to earnest for her own good? That's Megan Mullally as Lydia, a Midwestern mom who moves to Hollywood to pursue her daughter's dreams of stardom and she's the latest edition to the band of misfits on 'Party Down' (Fri., 10PM ET on Starz).

Mullally's seasoned comedic chops are nourished by her co-stars Adam Scott, Ryan Hansen, Martin Starr and Ken Marino, whose behind-the-scenes pranks of leaving little gifts behind in trailer toilets feed into the insanity of the show.

The actress who may be best known as the bodacious Karen Walker on 'Will & Grace,' chatted with TV Squad to talk about her new role on one of the most critically-acclaimed, ratings-challenged shows, 'Karen: The Musical,' Children's Hospital' and a sing-off with 'Party Down' alumna Jane Lynch.

What is your role on 'Party Down'?
It's my new favorite show. I'm playing a dorky screwball caterer Lydia in the company called Party Down. [She] is this clueless, bright eyed and bushy tailed woman from the Midwest who comes to Hollywood with her 12 year-old daughter Escapade who is going to be a star. This season we're catering backstage at a def-metal concert and we're catering an orgy. I have a crush on every person in that show including Lizzy Caplan. I would literally make out with any of those people although that would be kind of disgusting because three of them are in their 20s and I'm 51!

If you were a rock star, would you yearn for a normal life? That's the question on 'Party Down' (Fri., 10PM ET on Starz). Fictional rocker "Jackal Onassis" is a Marilyn Manson-style star who has grown tired of the fame, the money and the endless groupies. So he decides to swap lives with one of the hapless 'Party Down' employees.

It's hard watching 'Party Down' knowing that this show will likely not be back for a third season. But, set aside all the casting news -- virtually all of the cast is committed to new pilots and series star Adam Scott is going to 'Parks and Recreation' -- and 'Party Down' is just as enjoyable as it was last season. The writing remains sharp and quick, while the sardonic wit that makes this show so special continues to flourish.

The season 2 premiere finds the caterers backstage at a concert of the fictional rocker Jackal Onassis (Jimmi Simpson). Henry (Adam Scott) has been promoted to team leader and Ron (Ken Marino) is no longer with the team, but runs into them at the concert. Kyle (Ryan Hansen) and Roman (Martin Starr) are still there, not finding much success in their careers yet.

Created by Paul Feig and produced by Judd Apatow, 'Freaks and Geeks' is one of those rare television treasures that no one saw or appreciated until it was too late. Okay, that's unfair. Critics, the press and the loyal fans who did find the show on NBC immediately knew that it was something special. Unfortunately, it didn't find wide enough appeal to last beyond its first season.

Ironically, the show's cast of virtual unknowns now reads like an all-star comedy troupe, which is a testament to the brilliant casting that went on behind the scenes of the show. Finding such talented kids, and then coupling them with brilliant writing crafted on of the most revered television shows of all time.

Freaks and Geeks is not only a cult classic among TV fans, but it's also one of TV Squad's favorite "Ol' Yellers". Those are the shows that were taken out back and shot down by the networks before they had a chance to fully develop, despite the crying, whimpering, snot-producing pleas of those who loved them most. It may not be clever, but it sounded a lot nicer than "stillborns".

So it's no surprise that the show made a cameo appearance in a recent AOL interview with mega-superduperstar Seth Rogen on the heels of his new movie Observe and Report about a rogue mall cop who is more tazer-happy than the campus police at the University of Florida.
