HAHAHA! Those were my EXACT thoughts.
I looked at my wife and said "what the crap is he talking about... wasn't that .50 cal sparkly blue and pink?"
They are all TERRIBLE actors. That argument between him and his wife over that gun was COMPLETELY staged. It was so incredibly forced.
If its an actual Damascus blade, it could be worth quite a bit, but I feel the same way.
And what the eff... I haven't seen his daughter ONCE in this entire episode.
