The one ad campaign on TV that I remember seeing and thinking it was cool is an ad that I didn't even recognize as a commercial at first. It really held my attention for that reason. Then, at the end, I thought, "Wow. Cool commercial. I didn't see that coming."
It was the Levi's "America, Go Forth" commercial featuring a poem by Walt Whitman.
