On Thursday's penultimate Survivor: All-Stars, Big Tom became the latest dimwitted castaway to get knifed in the back by Boston Rob. "I'm still bleeding," cracks the 48-year-old speaking-impaired Virginian, who hints that he may exact some sweet revenge during Sunday's finale (8-11 pm/ET). "If Rob makes it to the final two, I will be proud to tell him what I think." Here's hoping it doesn't come to that. (Go Rupert!)
