I'm late to this party, but I would:
-Pay my debts (~$70,000)
-Pay my parents debts (Not sure how much but <$100,000 I'm sure)
-Buy my parents a nice house, and, since they live on a farm, new barns, tractors, etc. They've been using very old machinery for a long time now. They deserve good stuff.
-Buy a new-ish car for myself. I'm driving a 2001 pickup. It's fine, but showing its age.
-Give $5 mil to a very good friend of mine. He wants to be a writer, but he's stuck in the work-a-day world.
-Give a lot to another friend.
-Invest at least $50mil of it
-Go on a fun ~$50,000 shopping spree, buying things I've been wanting for a long time.
