Grey's Anatomy, House, ER, M*A*S*H and Scrubs Docs Unite — Watch Video

Here’s something you never thought you’d see again, especially after this confessional: Patrick Dempsey in scrubs.

In the ultimate medical show “crossover,” the Grey’s Anatomy alum is joined by fellow TV doctors Noah Wyle (ER), Alan Alda (M*A*S*H), Lisa Edelstein (House) and Donald Faison (Scrubs) in a new commercial advocating for annual check-ups.

In the ingenious ad (produced by Cigna Health Insurance), the actors portray themselves and make clear of how little they have in common with their former on-screen personas. Knowing that they’re in no position to save lives, they preach the importance of getting to a real medical practitioner before gathering for an epic “TV doctor pose.”

Press PLAY on the video above, then head to the comments and let us know which other TV docs you would have liked to see in this commercial.
