For me it's the Cowboys. I know the Phillies just lost to the Yankees, but otherwise the only time the Yankees upset me is during the winter meetings when free agency heats up. My team doesn't face them in any significant capacity on a REGULAR basis.
However, the Eagles/Cowboys are one of the more heated rivalries in sports, and thanks to OS and the wonderful Cowboys fans here, I've developed a new-found HATE for the Cowboys.
Whereas it use to be I love to see Dallas lose. It's now I love to see Dallas lose so that ODogg, Freelance, WellWell, elgreazy, Andromada, and perhaps a few others suffer through disappointment.
