This is an old story, but a fascinating one nonetheless. (Also, I discovered it only recently.) A contestant (Charles Ingram) on the British Who Wants to be a Millionaire decided that he wanted to win the Big One—by hook or by crook, as they say. It’s an incredible tale of cheating, and using exceedingly simple means to gain answers that he didn’t know.
And then they made a TV episode of the whole affair. It’s awesome. Go watch! (There are eight segments in total; watch all of them.)
