Okay, guys, we're trying to make the clues a little more challenging! So here's my challenge to YOU: give us your best guess WITHOUT using the internet to search for clues! Come on, that's not the spirit of the game! Watch as reporter Bridie Barry offers up the first clue as to the topic of this week's episode of BackStory's signature series, "The Revealer." Then enter your guess in the comments section. On Thursday's show, we'll read the name of the first person to get it right!
