Tim Jo, 'The Neighbors'
You know him as: Alien teen Reggie Jackson / Why we like him: It's no easy task being both a dorky kid going through troublesome teenage years and a clueless alien trying to pass himself off as a human, but it's one that Jo makes seem both simple and fun. He plays both sides of Reggie well, and manages to do so while still being charming and adorably naive. / Where else you've seen him: Alex Chang on "Glory Daze" and Dewey on "Greek."
