"Expect some below-the-belt humor when Homer Simpson undergoes a colonoscopy. The star of Fox's The Simpsons will be screened for colon cancer in a special animated bit on the "Stand Up to Cancer" fund-raiser airing on ABC, CBS and NBC Sept 5. In the segment, Marge makes a shocking discovery as she and a doctor look at Homer's colon on a TV monitor. "There's his wedding band! He told me he was getting it polished!" she roars in disbelief."
