Where was I.
Oh yeah. Hordes of fanboys and fangirls.
Before I die, I'll go around to a bunch of places with a friend and get a bunch of blurry lousy pictures of myself doing completely conventional everyday things. Some of me eating, a few half-obstructed shots in a supermarket. Half a dozen at gas stations. And I'll write a bunch of short stories or journal entries or emails, based on things that haven't happened but that I feel are moderately likely (or, even better, on multiple sides of this moderately-likely thing, so it'll be ready whether the event happens or not).
And this friend of mine will, after I die, occasionally release a photo or a story or a sighting. "He's not dead! He was seen in the In-and-Out Burger!" "He's not dead! He wrote this article about current events!" "He's not dead! He just went home!" (cue blurry picture of me on Mars, or something.)
Just because it'll let me continue screwing with people's minds even from the grave.
