Duh Commercials

I can't stand any of the versions of the Duh / car commercials.

This is how I see it... if you are in a conversation and you make a statement and the person you are talking with responds with 'dug' that usually translates to:

goes with out saying (stupid, dimwit, idiot, dummy, etc.)

So are these commercial implying we are inept if we don't buy one of those cars?

Question: Feeling insulted?
Response: duh
