First Event: The reign of Pharaoh Hatshepsut in Ancient Egypt. Yes, I know it's not really an event, but still. One, because I want to know how those dang pyramids were built; two, because it's Hatshepsut, people, keep up (http://en.wikipedia.org/wiki/Hatshepsut
for the unaware); and three, because I think learning Ancient Egyptian would be freaking awesome for a language geek like me.
Second Event: A speech given by Martin Luther King, Jr. I would have loved to have been able to listen to him speak.
Third Event: The arrival of Kleopatra into Rome. (I know, I know, I skip around time-wise. Sue me.) Because that would have been so utterly opulent, so insanely in-your-face, that it would have been breathtaking.
Fourth Event: The coronation of Elizabeth I, because I love that period in history and I really would have loved to offer some hygenic advice.
Fifth Event: I would have loved to have been in the Tower of London when the two Plantaganet princes mysteriously vanished, because I want to know what happened to them, damn it.
Bonus Event: The room where they broadcast the Battle of Britain.
