You'd think everyone would want to catch a glimpse of sexy vegan Alicia Silverstone in the buff, but Comcast Cable in Houston pulled a PETA ad showcasing a fit and naked Alicia. The 30-second spot was already paid for and scheduled to run more than a dozen times in the Houston market, but the nudity was apparently too hot for the city. On the bright side, Alicia can be seen in all her naked vegan glory at PETA's web site!
