John GoodmanA slimmed-down John Goodman visited with David Letterman on Wednesday night to talk about his shocking body transformation, admitting he was "pushing 400" pounds before cracking down recently. His motivation? "I was breaking furniture, for Lord's sake!" he joked.

"[I'm] getting a lot of exercise, I feel great," he told the astonished 'Late Show' host. "It's going to be an ongoing process for the rest of my life."
