Ken Jennings from Jeopardy! here, wearing out my welcome. AMA!
I was on Jeopardy so long ago that Friends was still on TV and no one took pictures of their food. I'm currently back playing on their "Battle of the Decades."
I'm now the author of the Junior Genius Guides for kids. They're fun!
Edited to add: Thanks everybody! I can't be with you here anymore but you can always follow me on Twitter or do my "Kennections" trivia puzzle in Parade or my Friday news quiz on Slate. Today we have John Hodgman! You don't have to do any of that stuff, though. We can still be friends.
