"Grey's Anatomy" star Patrick Dempsey's rescue mission in Malibu this week was even more badass than we thought -- just take a look at the scene of the accident!!!
TMZ broke the story ... a teenage driver crashed and flipped his Mustang on the road right outside Dempsey's Malibu home -- and the actor came to the rescue, crowbar in hand to pry the doors open.
Dempsey successfully pulled the driver from the wreckage -- a 17-year-old named Weston Massett -- who tells TMZ, when he opened his eyes, the actor was looking right down at him.
Massett asked, "Are you famous?" ... and Patrick coolly replied, "I'm a doctor."
We're told Patrick called Massett's mother and told her about the accident -- keeping her calm the entire time. Massett was then airlifted to a nearby hospital, and Patrick followed to make sure the kid was okay.
Miraculously, Massett suffered no serious injuries -- just a concussion and a "stretched" optic nerve. He's expected to make a full recovery.
There was also a passenger in the car, Dylan Miller, but thankfully we're told Miller suffered no injuries whatsoever.
Wear your seat belts, kids.
