So What Will You Do When You Win the $540 Mega Millions Jackpot Friday?

So what will you do with your $540 million—the largest lottery jackpot in world history?

Someone will win a record-setting Mega Millions jackpot—if not on Friday, then an even bigger prize later.

It's easy to think of how you'd spend $1 million or so. But that much cash? Wow, so many decisions to make.

Would you move to another state? Another country? Or would you stay put in Upper St. Clair?

Of course, you'd give a lot away. What charities would get some big bucks?

Any vengeance plans, like buying the company you work for and firing the bosses?

What luxury items would be the first on your list?

(And for those of you without a ticket, you have until 9:59 p.m.)
