Favourite advertisements?

I hate ads alot. But there are a few that I really enjoy because they are just so damn smart (like digital camera ads). What are your favourites. This is one of my new favourites because it's so creative. The line of underwear is called "Kaleidoscope" and they decided to create a human one. Ingenious!

I like "So easy a caveman can do it"

The Geico Cavemen are getting their own show in the fall.
