Happy 100th episode, you best darn medical comedy on television, you. Zach Braff directed this loving homage to my favorite movie of all time, The Wizard of Oz, and the shout-outs ranged from a Toto song on J.D.'s iPod to a makeshift yellow brick road through the halls of Sacred Heart. Not to mention ruby-red sneakers; paying no attention to that man behind the curtain; a melting wicked witch; "lions and tigers and bears, oh my!" and an "oil can!" for good measure; and a potential heart donor named Ray Bolger. (Although, if I'm gonna let my geek colors really fly, I have to wonder if it'd be more appropriate to call him Jack Haley, since the Tin Man's the one with the heart all along....) And yet with all these theme-y delights going on, I have to say my favorite moments were those not necessarily having anything to do with the metaphorical journey to the Emerald City: for instance, Dr. Kelso's genuine appreciation of his own commemorative bobblehead ("bobbley, bobbley, bobbley...") or Elliott's bordering-on-perfection retort to Dr. Cox, "Oh, really? Because you never went to assface school, but you seem to be an expert at that." Well, maybe that's a big fat lie, because my actual favorite moment has a lot to do with Ted's a cappella band crooning "Somewhere over the Rainbow" and making me cry like a little girl. I never thought they'd be able to top their own version of the Underdog theme song from Season 1, but I stand corrected. Bravo, boys. Now pass me a hanky. As for the second episode of the night, I can only say: Olivia Walton, Jennie Lowell and Michael Bluth all in the same half hour? Add Elliott's Jewish robot groom and an ostrich wearing Turk's red Kangol cap, and I'm officially spent.  Chana Shwadlenak

The Shield
I once wrote (though I'm certain I stole it from someone else) that The Shield is like a tweaked-out cop show that's been awake for four days straight. Tonight I've eaten way too much ultradark, fair-trade chocolate and I'm so sensitive to caffeine that I'm buzzing like a cicada, so this is like watching the cop show on meth... on meth. Or, as my junior-high math teacher might've said, meth squared. (Hey, I spend much of my time watching TV, OK? An overdose on a 71-percent-cocoa bar is about as dangerous as life gets for me.)

Anyway, buzz or no buzz, lots happening once again. Kavanaugh hovers ever closer to Vic and the Strike Team; Lem does his best to pretend to play along while protecting his guys; and Vic and the boys decide to help themselves by helping Lem... for now. In the meantime, we've got a sex-slave ring, tension between Claudette and Dutch, a witness' missing brother and a tough new P.D. named Becca. Oh, and Shane's "chee-chee" joke? I heard it years ago as something called "bunta." Which still can't be as painful as what Tina did to the guy who tried to attack her (not that he didn't deserve it). Things are certainly getting even more interesting now, with Vic meeting Kavanaugh, Corinne figuring out that Kavanaugh's trying to play her (and telling Vic about it) and my now-weekly realization that Forest Whitaker is a killer in this role. Nice scene between him and Michael Chiklis, too. And with Kavanaugh's knowing chuckle after they shake, I'll again end with what's becoming my Shield mantra: Uh-oh. Michael Peck
