Here are some one liners...
30,000 Dead in Lisbon Earthquake and Tsunami -- Yep... they blame the Jews. I also talk about earthquake preparedness.
Battle of Puná: The Beginning of the End of the Incas -- Francisco Pizarro kicks the snot out of the natives in a 100 to 1 fight. I talk about how impossible this might have been 50 years prior without the discipline they learned in Italy fighting the French and the Swiss.
Our Lady of Guadalupe and the First Native American Saint -- A vision of the Virgin Mary first appears to Juan Diego, an Aztec convert to Christianity. He builds a church in her honor, I also talk about the appearance of idolatry (which the Franciscan Monks share with me) and my experience with a middle school Spanish teacher.
