Whistlejacket by Stubbs. You can see it in the National Gallery (providing they haven't loaned it out).
Notice how there are two arms outstretched. What else was two? That's right - The Twin Towers. And the horse and boat are symbolic of mans interaction with fish. And no fish were killed on 9/11. Coincidence?
Yes, I tried to find the video but youtube is blocked in my work. She was on her way up to save the horses!
