Buy the board and cyber hang one liberal a month. Love to do it more often but we have a liberal shortage as it is!
Considering that you'd be taking out five posting ones with each demise, yeah, the shortage would be critical quickly. OTOH, harvesting puppets makes for great firewood stacks!
As to the 20 million....
First, spend about 5 of it to arrange things so moochers approaching me would silently cease to breathe.
Next, pre-pay a bunch of utilities and routine monthly bills. Actually pay them ahead for about twice my projected lifetime. It would result in leaving money on the table but I'd be covered for various price/rate increases for life.
I'd give careful thought to where I want to live....because then tax levels would be of no importance. I might like to replicate the house I live in perhaps in a different location. Not easy to find a better one mainly because no place has a 100% year-round perfect climate. That could mean keeping this house and building another with complete duplication of clothing, appliances, etc. After all the cost of migration twice each year would be of no import except for the inconvenience. No new computer; TV; vehicles. I like what I have and would try to closely match them at the "new" or "second" home.
Then hire a damn good estate specialist:
A good comfortable amount should go to offspring but not so much as to deaden the worth ethic. Probably I'd leave less than way that most would imagine. No animosities; just don't want to create a wastrel.
I'd like to fund the education of several young people who have treated me well and ensure they have, upon graduation, enough of a cash cushion to be free to travel (for a year or so) and ultimately relocate to a place they want to work and live.
There are a couple of charities I'd probably give something immediately. Perhaps fund some specific projects. Beyond that, an endowment on which they could draw the interest BUT with a poison pill so if they diverted from the purpose for which they were established they'd lose it all. Maybe just take it and throw a beer bash. Or put on a big fireworks display. Let them see it go entirely to what they'd consider "waste".
Yeah, having 20 million would have fun. If it didn't kill me.
