Clever Advertising

Apple has some of the greatest advertising campaigns ever. I love their tv commercials. They are entertaining, simple, and humorous. Their website has some new ones they've created.
City bank also created some of the best tv commercials because they are so silly. See here.
Sony has some memorable ones as well. Their use of color to make their point is really creative. I'm sure you've seen the bouncy balls, but there are quite a few more as well.
And then this one... which was banned, but is really funny.
