Today, in attempt to prove a point, I played a fun "game". I think you should do it as well; it's all kinds of geeky historical fun. Without the aid of a computer, or lifelines, write down as many US Presidents as you can in 10 minutes. I promise, it's not as easy as you think.
There are 43 men who've held the title of Commander and Chief. I was certain I'd only get half; but surpassed by goal with 24 of 43. 55.8 percent, thank you, thank you. Without a decent church history knowledge, I doubt I could have come up with 20.8 percent of my 55.8 percent.
After completing said self imposed task, I checked my list against a full-blown history of the Executive Branch's head masters. Duh. I missed some easy ones. (And I swear at least two or three that have to be a joke.) But I'll tell you what, those important guys are next to impossible to remember when you're trying to do so. I can't tell you what or who exactly because I don't want to give you any hints.
So... how many did you get? Did you accidentally add any prophets to the list? Any self-realizations as you played?
