Whenever anyone[1] says they have a question for me, I quickly volunteer up the answer, "The Defenestration of Prague," preferably before they ask the question itself. If that doesn't fit, "Praeseodymium" and "Forty-Seven" are also tried.
Anyway, if you've ever wondered what the Defenestration of Prague was … well, wonder no longer.

[1] Well, anyone at home.
My mother's default pre-question answer was always "Jimmy Carter", but I think I like this better. I may steal it.
Symplegma.
