Well first I would set aside a royal arse-load of it so as to ensure myself a nice prime and proper multiple PhD style education.
(PhDs, why get just one? )
After that I would, err;
ok honestly?
By myself the complete works of every science fiction author from 1930 on.
And a big huge ass bookshelf / mansion to store them in.
And then I would sit down on my ass and read them all.
(that is actually my primary motivation in life, or at least it was/is before it got clouded with tons of other stuff. . . . now its aimed more towards helping other people, but why not go back to basics? )
Purchase my Grandmother a new Knee / Hip / Whatever Other Miscellaneous Bones She May Have Injured.
Setup a foundation that runs of the INTEREST of some of that money (a mere four billion dollars at 3% interest yearly and. . . . ) to help out old ladies who need medical procedures done.
Give a royal wad of cash to Seattle Children Home, they deserve it. Helped me get my life straight. (and with risk of using somebodies real name here, lets just say that one Martin Bullard would end up a VERY VERY rich man. Thanks Martin.)
Hire privet death squad to go around and assassinate companies who do shit I don’t like
I didn’t just say that.
Make prozac manufacturing plant, sell it cheap, just to piss off the company that is in charge of selling prozac big time. Hell I would likely start selling almost all of those overpriced prescription drugs cheap.
Start a “we give you free AIDs medicine if you stop f*cking people” campaign.
Remember to include clause in contract above about “balls being permanently chopped off if terms of contract are violated” .
Betcha I could get that AIDs thing licked in no time. (seriously, easiest disease to prevent EVER. I still can’t figure out why it even exists and spreads for that matter in developed countries. . . . in the undeveloped world sure I can understand, but come on, condoms are cheap, use them damnit.)
Set up special interest group to try and get laws passed requiring a license for having children. (after spending a few years in SCH a person gets the idea that there are a ton of parents in this would who SHOULD have been required to undergo some sort of basic preliminary examination. . . .)
err, I guess I still would have about 42billion left, hehe.
err, 126 million a year at three percent interest;
I would choose 31 random families each year to make rich (4 million each, with two million going back into the account and / or into some sort of emergency expenditures account)
