Pamela Anderson is keeping herself busy while in Sin City. The longtime PETA supporter took a break from her stint in illusionist Hans Klok's stage show to dish out portions of a faux-turkey entrée during an all-vegetarian pre-Thanksgiving dinner at a homeless shelter in Las Vegas yesterday. "The holiday season can be especially hard for those who find themselves homeless, and it's murder on turkeys," says Pam. "With so many healthy and delicious options nowadays, it's easy to have a holiday meal that gives even turkeys something to be thankful for." Question is: were the recipients of the meat-free meal thankful, too?
