You win the USA Power ball for $1,000,000,000 what do you buy first?

I'd probably pay off my remaining bills/student loans. After that, I'd hire someone to manage my assets, make sure my money makes more money, etc. From there I'd take care of the various repairs needed around the house, fix up my truck a bit, probably get another more fuel efficient second vehicle, and then... honestly, I don't know. Probably just tackle various side-projects that I've been putting off because of work/life.
