A.K.A. "The Dork"

Hello? Yoo-hoo! Hi! Say, have you been tested for Attention Deficit Disorder? You've got your head in the clouds, my friend, but it helps make you a more interesting person. Your friends may think you're a bit of a dork, and you may make the wrong decisions on occasion, but you're a sweet, happy person who's on the right track in life. You may want to hire a bodyguard, though...you're the type to attract stalkers.
