Great and Possibly Not-So-Great Rivalries

This morning, as I was staring at the leaves in my front yard, a yard that I had just raked yesterday, I started thinking about rivalries. Rivalries like the one I was currently engaged in with my neighbor's maple tree. Unfortunately, the maple tree won this round, but the thing about rivalries is that they are not decided by a single battle, they play out over time, each side taking victories and defeats. Unfortunately, the ranking got a little congested at number two, however, number one was never in doubt.

379) Cowboys vs. Washington D.C. football club (this one is funny)
296) Packers vs. Vikings (only one side views this as a rivalry, the other side thinks it's cute)
178)

2oo.) Nirvana vs. Pearl Jam
