Car show season (and the people they bring out) around the corner

We've all (or a majority of us) have personally seen or heard these comments before. If they are directed to you and/or your vehicle, what waste any time rebutting these kinds of comments. I have found that simply (and somewhat loudly) saying "Bye" and walking away is the best medicine for blowhards. It really gets their goat when you don't engage them.
