TMZ has obtained the 911 call made after the horrific car accident involving Puck from the "Real World: San Francisco" -- a call that was only made possible because of the heroics of his 8-year-old son.
After Puck drove the car into a ditch in San Diego last month, his son managed to crawl out of the wreckage and flag down a person with a cell phone who then dialed 911.
With injuries to several internal organs, Puck's son calmly explained the situation to the caller -- who relayed the info to the 911 dispatcher. Both Puck and his son were hospitalized with multiple serious injuries.
As we first reported, CHP officers believe Puck was drunk at the time of the crash.
