Okay I have a couple of favorites, I'll post the link as well.

One of them is the DQ waffle and soft serve ones. Gawd I literally cracked up when I saw it. http://www.youtube.com/watch?v=vpV8e6CBA1w

I'm sad that they don't show these Amp'd Mobile commercials anymore. They were some of the commercials that didn't annoy me. Here's one of my favorite ones. http://www.youtube.com/watch?v=TUNKQhLIJZQ
