Nope,
His arm was replaced by a cybernetic arm after a robot saved him from drowning while trapped in his car. His car was under water, along with another car, after an accident involving that car with a little girl inside.
Spooner could see the girl in the other car and demanded the robot save her instead. The robot jerked Spooner out of his car, and as they swim to the surface, Spooner watches as the girl and her car disappear into the gloom.
The robot who saved Spooner explained that he had a higher percentage of living through this rescue than the little girl and that's why the robot saved Spooner instead of the girl.
This is the whole basis of Spooner's hatred of the robots:
They are too cold and calculating. The robot did not consider that a human, though not as calculating, would have tried to save the child and not the full grown man. (Who wouldn't?)
No matter the odds.
You deserve a smack on the forehead!
Please don't get high before watching a movie again!
