Buy Your Mega Million Ticket, Please

I was just talking to a co-worker and she was telling me she wasn't buying a Mega Million ticket.  I said, "Do you want me to give you a dollar?"  She laughed and said, "No."I know you might not win...but there's that MIGHT not.  There's a chance you could!  A chance at $586 Million Dollars.  I'm almost breathless thinking about that because I bought my ticket, cash option, so I could win $316.5 Million Dollars.  I can't even imagine.  Let's dream together!

What's ONE thing you'll do if you win tonight?
