Declare myself ultimate ruler of Earth until death, then have everyone I don't like killed, I'd get laid, a lot, release prototype right now, slap a *****, set up wireless, global-super-broadband internet, destroy 4chan, destroy scientology and kick every scientologist in the balls before kicking them off a cliff, in the case of hot, female scientologists I'd have my way with them and then kick them off the cliff.
Oh also I'd round up all the twitards, conspiracy theorists and other stupid folk, put them on and aircraft carrier, get in my monster truck and chase the down, crushing them or laughing at them as they leap into the sea.
Then do whatever I wanted as ruler of earth for the rest of my life.
