I had this odd dream a couple nights ago that I got to spend a day with an interesting historical person. In the dream I was supposed to have been able to choose but somehow I wound up wtih Enrico Fermi. Now this is nothing against Enrico Fermi and I explained to him that I was very much impressed with his accomplishments but he wasn't who I wanted to hang out with and there was clearly some kind of mix-up. As it turned out, he was pretty cool about it and there wasn't anything to be done; I could have the day with him or with no one, so we walked and talked. Neat, but I expect other people had better experiences.
The point of the thread I would hope is reasonably clear: if you could hang out for a day with historical person of note, who would it be? What would you want to do?
