Well, I have a feeling I'm gonna like Crazy Horse vs. Poncho Villa. I also liked US Rangers vs. NKSOF, Saddam Hussein vs. Pol Pot, and Joan of Arc vs. William the Conqueror.
Also, what do you think of THIS for a joke match: Twitards vs. Narutards (the obsessors over the crap-tastic Twilight saga vs. the obsessors of Naruto).
