Doctors McDreamy, Hawkeye, Cuddy, Turk, and Carter are scrubbing in.
Some of TV's top docs got together for a Super Bowl-caliber commercial for health service company Cigna.
The super surgical squad includes: Patrick Dempsey, who played Dr. Derek "McDreamy" Shepherd on "Grey's Anatomy;" Alan Alda, who played Captain Hawkeye Pierce on "M.A.S.H.;" Lisa Edelstein, who played Dr. Lisa Cuddy on "House;" Donald Faison, who played Dr. Chris Turk on "Scrubs;" and Noah Wyle, who played Dr. John Carter on "ER."
"I have no idea what I'm doing, I'm just a TV doctor," Alda admits in the "TV Doctors of America" spot, which promotes annual check-ups.
