That's impossible, 2.147billion is max.
What if you lost a million coins in a 50/50 :o?

I would be so sad and angry. What if you got 70 luminous pokemon from lucky dip?

Well I'll be the luckiest dipper in creed.
What if you got hold of a chance to peek on humanity's darkest history?

I would keep it a secret and be shocked at the same time.
What if you had a choice of picking a deoxys, palkia, or dialga in this world which one would you choose?

I would love to choose deoxys, since it looks so cool and has different forms/modes. What if you became an element? What would you like to be?

I would like to be carbon because I would like to be the common element to all organic matter.
What if the earth suddenly stops revolving?

I would hope that it would stop in a month so it would be early summer for me.
What if you lost all of your 5 senses?

I would try to kill myself since I can't do anything. What if you could have any one wish you want? What would you wish for?

Sorry, came out twice somehow.

I'd choose Air Gear world!!! I'd be the holder of my very own Regalia :D
What if you saw your dopleganger in a crowd... What would you do?

Walk up to him and say - "There's place for only one me!" - and punch him square to the face.
What would you do if you were caught in a tornado?

Um... try to stay conscious and watch the inside of the tornado, maybe even film it and send it to some lab :D
what if while walking to school, or back home, you were suddenly kidnapped?

I'd quietly try to escape the hands of the kidnapper, or go and run away after I get a chance... parkour will always come in handy
What if we all ran out of questions in the world?

then... I don't know, I guess the world will be quite boring O_o I like keeping my self curious about all the unanswered questions XD
what if... one day, you wake up without both your legs?

I would start freaking out and call the police and hospital. What if you woke up a week from now and found that you had been asleep for a million years? How would you feel about that?
