What will you do?

Lately, the news of the New Zealand couple flee out the country after their account has been wrongly credited with NZD10 millions which make them an instance multimillionaire. After they wrongly received the money. they transfer the money to their overseas account and flee to China. I am wondering what I will do if I am wrongly transferred with 10 millions into my account? first thing come to my mind.. remember to take a snapshot of the account balance first.. :P At least I am once a millionaire, even for a very short period :P Next? Will I escape with the money??? I really don't have the answer.. first of all, it will make me a criminal.. which I think is not so an idea situation :P what I will do? I think only wait till it happend then I will know :)
