The Audi commercial with the Eco police - I get what they were trying to do there, but to me it just felt like they were re-inforcing the "smug jerkoff" stereotype that hybrid and "green" drivers already have. Not the best way to sell a car, imo.
Actually, I thought they were busting the chops of the greenies, but I take it they think their car is green, so I put that one down as a fail.
The one I liked the most was the VW commercial with everyone calling the color of the car that passed by and slapping the person next to him/ her. When Stevie Wonder says "Red One" and slaps the guy next to him, and he says "How do you do that?" I cracked up. The other one I am surprised I liked were the E-Trade baby series. Ordinarily, I switch away when they come up (I don't think their cute, and I don't need to see barf), but these seemed a bit funnier. The one that had him away but having his stop loss orders triggered and saving him money is one of the few where I actually remember the product that was being pushed.
