Fight on Grey's Anatomy set

Patrick Dempsey, who plays Dr. Derek Shepherd on Grey's Anatomy, and Isaiah Washington, who plays Dr. Preston Burke, got into a fight on the set. The National Enquirer reports that Washington was yelling at T.R. Knight, who plays George O'Malley, when Dempsey told Washington, "Pick on somebody your own size." A source told the tabloid, "Isaiah became enraged and grabbed Patrick by the throat and shoved him back a few feet." The fight was broken up and Washington stormed off. However, he later told People magazine, "I've never been that close to [Dempsey] before. He has really pretty blue eyes."
