The Obama campaign attempts to take 30 seconds to name all of Mitt Romney's Massachusetts taxes and fees. Set to a piano can-can, the words dance across the screen highlighting some in a very funny way: "Docking fees - Undocking fees" and at the end of the mass of information comes the punchline: that was only half of them.

One of the funniest attack ads I've seen to date. Nicely done, Obama campaign creatives.
