"He's just napping in between takes," Dempsey joked.

DeGeneres thought that, in a similar vein, Dempsey should tweet a picture of her wearing a neck brace and an eye patch and holding some champagne. Here's what ensued:

"Grey's Anatomy" Season 9 premieres Thursday, September 27 at 9 p.m. ET. "The Ellen DeGeneres Show" is syndicated nationally.
