This one [and only because I don't think I've ever seen a more poorly done commercial]: http://www.youtube.com/watch?v=Ti7cfnaRTdQ
It's a lawyer commercial [I think]...
Why is there a squirrel?
Why is he dancing?
Why does he have arms, and why are they longer than his entire body?
And why, oh, why did this company allow the designer of this commercial to live???
