It's a mixed blessing to get cast as a main character's mom on a sitcom. On the one hand, you can be pretty certain that you're considered famous enough to be a draw for sweeps -- and what's more, you're not being asked to do "Celebrity Rehab." On the other hand, it means that casting directors are starting to think of you as old. But at least they're thinking of you! Which is more than I can say for half of the cast of "Celebrity Rehab"; bassist from Alice in Chains, I'm looking in your direction. Last week's "Cougar Town" continued in the tradition of casting guest star moms when Beverly D'Angelo, from "Vacation" and, most recently, "Entourage," played Laurie's mother; and last night, living legend Lainie Kazan guest-starred on "Ugly Betty," above, as Hilda's possible mother-in-law -- and definite grandmother-to-be to Hilda's unborn child. But who's preceded D'Angelo and Kazan in the Annals of Great TV Mom Stuntcasting? Editors Julie Klausner and Tara Ariano picked their ten favorites after the jump.

Because I have normal, loving parents, I've never been the object of any of those late-night, gin-addled talks about whether I was their least-favorite child. I'm not saying my family is perfect, but I think that, with the exception of Jon Gosselin and Lucille Bluth, most parents are subscribers to the conventional wisdom that if you don't want to raise a harem of sad sacks and jerks, you should maybe hold back in letting your kids know that you love some of them less than others.

Well, guess who was the last to get the memo, AS PER USUAL? Television's Jack Hanna, who went on "The Early Show" today to tell America which of his animals were his favorite. And just in time FOR CHRISTMAS. Read more about this chilling revelation after the jump.

11:01:29 AM Will Edmondson: So, Tara, you're TOTES ready for this question, LOL!: Are you on "Team Edward," or "Team Jacob"!?!
11:01:59 AM Tara Ariano: To quote Lucille Bluth: I don't understand the question, and I won't respond to it.
11:02:49 AM Will Edmondson: Well, I know what team I'm on, Tara. I'm on "Team 2012," in which a massive, apocalyptic disaster strikes the (fictitious) town of Forks and leaves nothing but a magma-filled fissure down Main Street.
11:04:07 AM Tara Ariano: If that did happen, a lot of (fictitious) people would be better off.
11:06:02 AM Will Edmondson: I'm going to go out on a limb and say that this movie wasn't directed at me and my demographic. But this was still one of the worst moviegoing experiences I've ever had. And yes, this is a blog, and the Internet and hyperbole. But I'm serious: watching "New Moon" was horrible.
