I like watching because well I am a broken individual. I like seeing how far people will go and trying to figure out why.
That being said even though I like watching it I can't for one moment imagine why anyone would go on the show and lay bare their lives for money. Unless of course they were looking to just get rid of everyone in their lives prior to that day.
A brief synopsis for those that don't know what it is :
a contestant prior to the show is hooked up to a lie detector and asked a series of questions (yes I am aware of the controversy surrounding lie detector tests I didn't come up with the premise). During the show they are asked 21 of those questions (yes/no) they win money at 6, 11, 15,18, 20,21 up to 500,000 for the last question. one wrong answer 9one that doesn't match what the detector said) and you lose it all.

You walk around like you're oh so debonair
You pull 'em down and there's really nothing there
I wish you would just be real with me
