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.
