CNN left the best ones out because they're a bit...colorful:
"Have you not noticed that Americans don't give two shits what Europeans think of us? Each email someone gets from some arrogant Brit telling us why to NOT vote for George Bush is going to backfire, you stupid, yellow-toothed pansies ... I don't give a rat's ass if our election is going to have an effect on your worthless little life. I really don't. If you want to have a meaningful election in your crappy little island full of shitty food and yellow teeth, then maybe you should try not to sell your sovereignty out to Brussels and Berlin, dipshit. Oh, yeah - and brush your goddamned teeth, you filthy animals."
