VIDEO: Grey's Anatomy's Jessica Capshaw reveals her favorite Calzona moments

During a recent set visit, we quizzed stars Kevin McKidd, Camilla Luddington, Justin Chambers, Caterina Scorsone and Jessica Capshaw to see how quickly they can recite tongue-twisting medical jargon - which also happens to be actual dialogue from the show.

Grey's Anatomy airs Thursdays at 8/7c on ABC.
