Here are some one liners...
War of the Roses: York vs Lancaster -- Negotiations break down and the King gets an arrow in the neck. Richard of York will become regent again as the King slips back into madness.
The Gutenberg Revolution -- The Gutenberg Bible will spark a revolution in thought not because of the Bible itself but because people will recognize the potential of the printing press.
When Is a Man Like a Cow? --When he is a prisoner. I discuss the idea of bailment and Dog the Bounty Hunter.
