Mojo, 1980?-10/1/2010. RIP Mo-man. I know your life had many bad times in it, and I sincerely hope I made your last few years here on Earth happy and comfortable, with as much love and yummies as your huge heart desired. I love you bud, have fun running in the pastures of heaven. Until we meet again...
