With an Academy Award and a Nobel Prize under his belt, Al Gore has become a kind of Renaissance celebrity. Not surprisingly, Gore's global warming lecture is a big seller. The Smoking Gun, a Web site, nabbed a copy of the speaker's contract for a 2007 "Environmental Media Lecture," which revealed some interesting tidbits.
