PHOENIX -- You might not realize right off the bat, but you've probably seen comedian Tom Wilson in action. Where? "Think, McFly! Think!"
Wilson played Michael J. Fox's nemesis Biff Tannen "Back to the Future," and later Griff and Mad Dog in the sequels.
Wilson is on stage at the Tempe Improv through this weekend, but stopped by to chat with Kaley O'Kelley, and serenade her with a song he wrote. He says it's quite a time-saver.
