What Do You Do the Day After a Powerball Win?

Let's imagine this is your life. You've won the (now) Powerball jackpot of $1.5 billion. That's $930 million cash payout in case you're wondering. In this scenario you still have a job. What do you do on Thursday morning? 

Kekeluv and I have been talking about what we would do the day after we won Powerball and we've both agreed that we would have to come in to work. We would have to let EVERYONE know. Gloating. After that, we'd basically give away cars and houses for weeks.

What's your plan?
