Dr. Philip Zimbardo is Professor Emeritus of Psychology at Stanford University, creator of the Stanford Prison Experiment, and author of numerous books, the latest of which is entitled The Demise of Guys: Why Boys Are Struggling and What We Can Do About It. Not only does he wear a Nice Toupee, he sports a dynamite Zapata Goatee.
He also wrote a book called The Lucifer Effect: Understanding How Good People Turn Evil. You can see he's a bit of a devil, but not truly Evil. He could probably kick my ass, but I would be a better person for it afterward. Z-Man, I salute you!
