The Deadmau5/Foo Fighters pile-up. The Foos performed something like 42 times last night and generally remained on-camera just about forever. But their best moment came after Dave Grohl's long-live-the-rock acceptance speech, when they let this blinky-eyed goon throw bass-drops all over "Rope." And, I mean, Deadmau5, wow. For sheer giddy televised ridiculousness, only Nicki Minaj came close last night.
