What were "medieval indulgences"? Were they a way for rich people to buy their way into heaven, and help corrupt priests to line their own pockets at the same time? "Indulgences" aren't mentioned in the Bible, but they became heavily used in the Middle Ages. Why? Listen as one of greatest Buzzkillers, Professor William Campbell, enlightens us on the fascinating complexities! Won't cost you a cent, Buzzkillers!

Most people believe they know what Adolf Hitler's plans for a post-war world would be -- German domination. After all, didn't he say, "Today Germany, Tomorrow the World"? Well, Hitler certainly expressed ideas along these lines, although there is no record of him saying it in so few words. The closest Hitler quote that Buzzkill Institute researchers can find comes from Mein Kampf (1925): "If the German people, in their historic development, had possessed tribal unity like other nations, the German Reich today would be the master of the entire world." Where does "Today Germany, Tomorrow the World" come from? Professor Nash enlightens us!

It’s more complicated and interesting than you can possibly imagine! Send out a distress signal for your brain!

But did Maya Angelou really say it? Join Professor Buzzkill as he sings out the answer!
