'King of the Hill'

In the "Dia-BILL-ic Shock" season premiere episode of King of the Hill, Bill, unwilling to change his sugary eating habits, is diagnosed with diabetes. After deciding to use a wheelchair (which he really doesn't need), he is befriended by a rugby player named Thunder, who teaches him how to be independent. But their friendship is strained when Thunder realizes Bill isn't really disabled. Watch it Sunday, September 28 at 8:30 p.m. on Fox.
