I'm two weeks late to the party here, lol, but you are not weird for knowing how old Prince Edward is! I'm a huge Royal Family fan, so it took me about .02 seconds to get the answer that night. My personal belief is that the Final Jeopardy category should always be either The British Royal Family, Boy George or 80's TV.
And I have to throw in my two cents about Ken, which is that my family and I are really enjoying him. No one is Alex, of course, but we like him. And we're glad he seems to be reading the clues a bit slower than his first few games.
