Well I now have the History Channel on. There is a 2 hour program about the Christian Crusades. We love that type of stuff in our house.
90% of the DVDs we have are related to history (Egypt, Pompeii, The Medici Family, Martin Luther, Rome, Czarist Russia, Ancient China, Samuri era Japan, etc) I can go to sleep before the open credits on just about any DVD the lovely Mrs_B can start.
