Klaus,
You're definitely a candidate for this film. Before firing that sawed off shotgun, you sure better take the extra time necessary to grab some effective ear protection! You might need something with more range by that time though?
If I were trying to attack you by breaking out your window with a ball bat, and after several whacks find myself only getting tired and THEN see you grabbing ear protection and a shot gun? Well, you'd be surprised how fast I can run when scared shi#less...
