Part of the fun of life is the mystery, and thankfully, I haven't had anything happen in my life that I need solved (aka, no one I know has gone missing or mysteriously murdered) so I'd pass. But I'd tell EVERYONE that I met a magical being!!! Can't wait to hear what they'd say.

I would want to know if there was an afterlife/what happens when you die.  (I don't believe in heaven/hell, so if the answer was nothing, I could totally be content and live with that!)

I don't think I'd waste the opportunity to find out who killed JB — I think I'd have to go as big as possible. So universe or God. Just so I knew for sure. But if that's off limits, I'd love to finally understand how 3D printers work. 

Considering I have no savings this would be easy I would want to know what happened to jonbenet

Hmmm? Who killed JFK or Are aliens among us? Can I do both? 

(And, FYI, if you keep the secret to yourself, you don't give up any money. Only if you tell someone are you penalized.)

FORGET THE UNIVERSE. I WANNA KNOW ABOUT THE DELPHI MURDERS. but would i want to know and not be able to tell anyone? would i become a vigilante? 

We talking like historical mystery? (If Jesus was real?)  Crime mystery?  (Jack the Ripper or JFK?) Or like life's greatest mystery? (Origin of the universe?) 

I have an opinion on every single one of those things, but I'd have to go with the origin of the universe. If I knew the answer to it & no one else did I'd still be OK w others pontificating about it because it's SO BIG in the grand scheme of things (arguably, it IS the grand scheme) that me knowing would still not make them believe me.

Literally cannot keep a secret, so I would have to turn down the deal. I can barely keep a friend’s surprise party to myself, let alone who killed Jon Benet. 

Not a chance. In the words of Mona Lisa Sapperstein, "Money, pleaaaaaaaase." 

You can get the answer to an unsolved mystery of your choice, but must keep the answer to yourself. If you tell anyone, you must give up all your life's savings.

Do you take the deal? And, if so, what unsolved mystery answer would be worth bankruptcy? 

A magical being offers you a deal...
