i would invent a time travel machine to travel back to the past, to the time you was born. my next step would be to fuck your mother and get you as kid, after i made sure to beat your mother up, so you will be born as a retard, i travel back to present, kill my present me with acid and your mother and you with a fire, burning down the complete house.
you would loose your mother and your dad (me), die on a horrible way and i would get money from insurance because nobody would know my present me died.
WIN - WIN Situation!
(somehow i feel bad for my minds now)
