Secret Life of Dr. Demented — Dan Gutman

Every American Wrestling Federation fan knows that, the evil Dr. Demented is the nastiest and most violent pro wrestler around, the man everyone loves to hate. He's always insulting the audience, inflicting pain on the good guys, and yelling his notorious catchphrase. And he always wins, one way or another.
So when fourteen-year-old Wesley Brown accidentally discovers the secret identity of Dr. Demented, he freaks out. Now that he recognizes the man behind the mask, Wesley figures he's dead meat...or worse. Wesley knows pro wrestling is just a big show, but he also knows that a monster like Dr. Demented can't be a nice, normal guy out of the ring...can he?
