Carell is a miracle in pink-and-blue-striped socks. He creates a character whose pain surrounds him like a hard plastic bubble. And the less he seems to do, the funnier he gets. He makes the name "Nietzsche" (which he pronounces crisply as "Neet-chah") inexplicably hilarious. And how to describe the way Uncle Frank runs? It's an intellectual run --- performed as if the act of running had been studied, broken down into its component parts, and then reassembled -- all analysis, no grace. It's almost inhumanly human, and pricelessly funny. But it's not just a sped-up silly walk, it's an authentic expression of character.
