I was thinking about that the other day. The conspiracy theory I most want to be true is "global warming is a hoax". Nothing but upside there.
Revise that: my actual number one hope is the "Jeff Mangum built some kind of time machine and saved Anne Frank" theory is right, but that's admittedly harder to believe.
I like to believe that he succeeded and that Anne is now a little boy in Spain.
Playing pianos filled with flames sounds like a rather significant fire hazard though. Doesn't sound like a very pleasant existence.
