Sort-of reality show "The Hills" is still keeping MTV alive! And its evil semi-star Spencer Pratt may be a prat but he is one smart cookie. When Heidi Montag, his inamorata, returns from lunch with Jenny, Spencer is sitting on the couch reading The Intelligent Investor: A Book of Practical Counsel, Benjamin Graham's classic 1949 guide to value investing. There's even a foreword by Warren Buffett! Anyway, according to Heidi, "Jen [Bunney] was telling me [Heidi Montag] that Lauren [Conrad] was saying Brody [Jenner] says that it was all Spencer [Pratt] who was spreading the sex tape rumors." (That would be the famed sex tape of Lauren Conrad and her once-and-current boyfriend Jason Wahler.) Pratt was once Brody Jenner's "manager-slash-publicist-slash-agent- slash-stylist! Deflection time! "He's such a little bitch!" says Pratt. Sure. Did Pratt fuel speculation about Conrad's sex tape? Almost certainly! But more importantly, was it a sound investment?
