It's no surprise that Fox News shouting head Bill O'Reilly, with his frequent temper tantrums and one-note commentary, can be accurately impersonated by a child. What is startling is that a kid could do it so well. "The Lil O'Reilly Factor" sets itself apart from lesser YouTube parodies by being fast, funny, well-written and executed without any verbal stumbles. Take the audio track down a couple of octaves and, with your eyes closed, you could mistake this video for the real thing. Adult online humorists should take note. And O'Reilly, if he's smart, will start scouting for Lil' Keith Olbermann, which could be just as devastating. [via Soup Cans]
