7. George the lobster
George the 20-lb, 140-year-old lobster is suspected to have been born around 1869 and has spent most of his life in the wild -- that is, except for the time he was captured and sold to a New York restaurant, in 2008. The restaurant claimed it never had plans to cook George, but rather to keep the world's oldest lobster as a mascot. Still, PETA rallied around the crustacean, demanding that he be returned to the ocean. Their protests were successful, and in January 2009, George returned to the sea.
