Check out this guy's collection of autographed baseballs. He's got over 4,000 signed balls and is in the Guinness Book of World Records. You don't want to steal from him though. His collection, which includes nine signed Babe Ruth balls and a ball signed by Marilyn Monroe and Joe DiMaggio, is in a bomb proof vault. Oh yeah, him and his wife are strapped too. She carries a .45 automatic!
