That "Saved by Zero" commercial for Toyota is probably the most painfully annoying piece of advertising ever created.  I assume some advertising jerk achieved his goal of getting an idea stuck in the heads of millions of people, but it begs the question:  Will I buy something because a song is stuck in my head, or will I purposefully never buy anything from Toyota ever again because they ruined my entire fall 2008 football season with the most annoying commercial ever?  Thankfully, as Consumerist points out, the ad has failed, seeing that Toyota's sales numbers continue to drop. 

Also, on the subject of automobile advertising, who exactly responds by purchasing a new vehicle?  I mean, it's one thing if you're ready to buy a new car and you're just waiting around for a good deal.  But what about the rest of us who don't have $20k sitting around just asking to be wasted on a new car?  I for one can't see myself ever deciding to buy a new car simply because I see a commercial for 0% financing.  That's just me. 

The other annoying ad I wanted to point out was that "Five Dollar Foot-Long" one for Subway.  I have to give them credit:  (1) I know exactly how much a foot-long sandwich costs, (2) I know exactly how long of a sandwich $5 can get me, and (3) I have an easy-to-remember song that will never cease to remind me of the facts stated in (1) and (2).
