Let's say you're in a bar watching the big game and strike up a conversation with this guy. Do not make any bets with him.

This is Mark Simon, a researcher for ESPN, who shows off an insane memory in this video by recounting the final out of the last 60 World Series. Or, more accurately, he names how each of the Fall Classics ended, since not all ended with outs (thank you, Bill Mazeroski and Joe Carter).

Impressive stuff, if not a little frightening.
