When early trailers were posted online for Lincoln, the new biopic from Steven Spielberg, the consensus was that star Daniel Day-Lewis, known for the research he pours into perfectionist transformations, was finding his way into character through the voice. Day-Lewis as Lincoln sounded nasal, deliberate, a bit pleading, and surprisingly high-pitched. In instant homage, Jimmy Fallon took a clip from the trailer—the president, urging a group of black-clad 19th-century men sitting around a table to make a change “now, now, NOW!”—and redubbed it as Pee-wee Herman.
