Don't tell anyone, set up a big party with personalised gifts for my closer friends, and invite them all over. Don't tell them what it's for, just tell them they really should turn up. Any that do get their expensive gifts tailored to their likes; the ones that ditch...payback's a *****.
Then move away, get a nice house, and occasionally give money away to homeless people on the street, maybe have impromptu games to win my charity for fun (in a non-exploitive way). Hell, set up a lot of money for my heirs, make something hopefully sustainable for generations. But, I would never be able to waste all that money on myself, and I wouldn't want to, so I imagine I'd be more than happy to share the fortune with those that need it.
Also, adopt an orphan, send them to butler school, and hire them full-time upon completion with promises of lifetime financial security and a place to call home.
That's what, $2 Million? Plenty to store away and spread around. I'm not going to be one of those rich people that hordes their money...for God's sake, there's people starving to death because they can't get a handful of change.
