Here are some one liners...
Mad King Henry and Woodrow Wilson -- The King is catatonic after he lost France, leaving his wife with a newborn son to rule England all by herself in secret. President Woodrow Wilson's wife, Edith, did something similar when he fell to a stroke.
The Aztec Flower Wars --The Aztecs need more people for human sacrifices so they start a war so that they can take prisoners rather than sacrificing their own people.
The Birth of Amerigo --Ever wonder how America got it's name? I make a bit of a joke out of it here. I'll be more specific when it actually happens.
