I'd shoot everyone i hate, rape all the chicks i like, yell at at my father, declassify all of my top-secret technologies (I.E, Zero-Point Energy, EM propulsion, Plasma Sword, ect.), make a bomb, blow up my high school, find Eric Bauman, Kill Eric Bauman, Become a famous internets ledgend, (probobly rip of NEDM or Numa Numa) and use an automatic weapon.
Yeah, then I'd cut my wang off, tie it up while its still hard, throw it at people, Then, if i know WHEN im about to die, cover myself with 20 pounds of high explosives, run into a high population center, and blow myself out of existance.
