If your character gets shot, quickly press P before the Mortician appears. Choose "Continue" and the game will resume from where your opponent began to shoot, rather than the beginning of that scene.
Kill Mad Dog
When you get to Mad Dog in the final showdown he'll say,"That's Bye Good Stranger".
Shoot him in the head before he shoots you.
He'll drop his gun, and reach for his other one.
Shoot him in the head again.
Mad Dog will die.
