Here are some one liners...
Buying a New Sultan -- Two brothers fight over the throne of the Ottoman Empire so one brother tries to buy the other off. After the other brother is captured by the Christians, the new Sultan pays the Pope to keep his brother prisoner. It was a lot of money. A whole lot. I also talk about how things get more expensive for those with less money.
Columbus: A Fortunate Mistake -- Christopher Columbus receives a letter including a map of the world that is WRONG but it spurs him on to organize a voyage west to Asia. I also talk about the Moon launch in the 1960s and the reasons why we try things and not just think about doing things.
