Well, I plan to be immortal, so this really isn't a problem for me. However, if I had to choose, I'd hold a convention for everyone who ever posted on an internet forum. There would be free food, so they would all come. I'd come out on stage, and onto a podium. There, I'd yell into the mike: "Do you like Mudkipz?! 'Cause I think they suck!" Then I'd take an atom bomb concealed behind the podium, yell "I just won the game!" and headbutt the nuke. Asplosions would commence.
Then the world would be saved.
