After putting a sum of it away in the bank, I'd give portions to my family.
Then I'd blow the rest on a decent house, that overly priced Darkwing Duck snow globe, a bunch of DVDs, Blu-rays and video games, comic books as far as the eye can see! And to top it all off I'll buy hundreds of packs of pencils! Then I'd build myself a cardboard box mansion and sit in it until the rain would come and ruin it. YESSSSS! Oh, and I'd also give some of it to those poor people.
