After a tense exit from Grey’s Anatomy, you’d better believe it took something big to get Patrick Dempsey back in scrubs. That something is a whole host of expert TV physicians gathering across space and time and television universes to tell you to watch out for your health, dummy! Joining McDreamy in the Cigna campaign are Alan Alda (Hawkeye on M*A*S*H), Lisa Edelstein (Cuddy on House), Noah Wyle (John Carter on ER), and Donald Faison (Turk on Scrubs). We’re pretty sure that Turk appearing without J.D. violates some kind of international accords, but we’ll let it slide so long as Dempsey gets his doctor pose in shape. He’s the most recent TV practitioner of the crew, but, dang, the man is rusty! Take a lolly and watch above.
