(S04E08) Man, I hate Woooo! Girls. And I'm pretty sure Bays and Thomas hate them too.

I mean, why would they devote an entire episode to them, then use them as a vehicle to demonstrate how both Robin and Ted (a WG by proxy) are currently single and rudderless in their lives? It was a nice little switcheroo, though; you go from being merely violently disgusted by the WGs at the start of the episode to really feeling sorry for them by the end. Oh, and rooting for that girl with the crush on Lily's friend Jillian to get her wish. But that's just me talking...

Jeffrey Tambor, aka Arrested Development's beloved George Bluth, is the
latest star to sign up for a guest stint on the HBO comedy Entourage. Tambor joins Sopranos star Jaime-Lynn Sigler and Gossip Girl's Leighton Meester on the guest star roster for Entourage's fifth season, premiering in September.

While both Sigler and Meester are set to play possible love interests for everyone's favorite semi-successful actor Vince Chase (Adrian Grenier), Tambor will be throwing a wrench into their plans for love when Vince suddenly discovers his propensity for older bald dudes. Okay, that's not true at all. Fact is, there's no word on what role Tambor will be playing, or if he'll be playing himself. Regardless, it's Jeffrey Tambor, so it will be awesome.

Since producers probably won't use my love interest idea (although I am totally copyrighting that right now, just in case) what are your opinions on Tambor's role? Should he be a studio exec? Mentor? Rival for Jaime-Lynn Sigler's affection? Post your thoughts in the comments below.

Jamie-Lynn Sigler is returning to HBO. The actress is set to guest star on the upcoming season of Entourage, playing the challenging role of actress Jamie-Lynn Sigler. Entourage has had a lot of celebrities appear as themselves over the years, ranging from significant (Mandy Moore as Vince's ex) to unremarkable (Kanye West). Fortunately, Sigler will get some significant screen time; her stint will last three episodes.

Details about Sigler's role are available after the jump. Between this news and the return of Gossip Girl's Leighton Meester, season five of Entourage is starting to look pretty darn good.
