How you would spend the money if you won the lottery.
Build an orphanage. Probably located in a third world country somewhere where homeless children run around...well, homeless. For real though, I would. This isn't some generic Christian answer, as nonchalant as my approach may seem. There is such a need to take care of our youth today, because they really are the future of tomorrow. Across the entire world and right here at home.
Oh ya, and a little bling for myself.
