Where to even begin with last night's American Idol Results Show Grand Finale Spectacular? While it may not have provided the knee-buckling rush of emotion that accompanies a shot of a moist-eyed David Hasselhoff witnessing the coronation of his prematurely graying Soul King, there were more than a few unmistakable moments of true poignancy: from George Michael's haunting "Praying For Time," to David Cook's landslide victory lap, to the Jonas Brothers' heartfelt plea on behalf of the Aging Sibling Pop Star Fund, with every dollar pledged earmarked for famine-relief among surviving members of The Jets, DeBarge, Hanson, and the like.

There were even some conquering summer box office heroes on hand, in the guise of Tropic Thunder stars Robert Downey Jr., Jack Black, and Ben Stiller, digitally inserted into a vintage Gladys Knight performance as her backing Pips. (Downey wisely decided to leave his black face makeup kit at home.) The entire video is available for purchase on iTunes—the profits also going to some (non DeBargeian) charity—but we've included a short clip above. In it, Black and Downey abandon their Pip-marks, leaving Stiller to handle the complex hand-spins and toe-taps of the legendary backing trio's choreography on his own. What follows is not exactly clear: Shortly thereafter, Black tumbles back into the frame with his pants around his ankles; a contented Downey soon follows. Are we to infer that the pair just rode an express Midnight Man-Train to Georgia? We'll just assume we are.
