Brilliant or challenged?

In a new commercial for Chase credit cards, two friends try to outpurchase each other to gain bonus points. I am assuming that using the new Chase system is a smart thing to use. Then why is the background music "Dueling Banjos" from Deliverance? This music is associated with being—sorry, this is not PC—retarded or at least too closely related. Seems to me Chase is sending a mixed message with these two guys. They say they're brothers. They seem a lot more like cousins.
