First of all who cares? Seriously. I personally don't think it's American's business if they are or aren't. They are personable guys who have an amazing show. It's engaging to watch and I love the people they run into. This show gives real American people a chance to show off their stuff and show us who they are. The historical facts about the items are also interesting.
America, how would you like your personal business discussed AT LENGTH on the internet? NO?

I thought not.
