Clark Gable 911: 'My Friend Just Got Stabbed'

It's clear the scene was chaotic, with one caller telling the 911 operator, "You really need to come, like now ... he's bleeding profusely and there's a f**king hole in him. I need someone here now."

Gable suffered lung damage from the puncture wound in his chest and spent a week in the hospital. We're told he's doing fine now.

One person was arrested in connection with the incident -- cops are still on the hunt for a second suspect.
