HillBilly BOB realized that with every new bank account opened, he's awarded a new gun. It's a deep south AMERICAN thing. BOB has now opened several bank accounts and collects a variety of guns.
Evidently, collecting guns is like collecting coins, comics, or stamps. That was cool in my youth. I suppose the gun collector might have a hard time bringing them into show-in-tell for a classroom event. I personally would be afraid to run into BOB at the local grocery store.
