Dear People of the 30th Century or Later...
I am typing this from the early 21st century, at a time when we have neither time travel nor antigravity belts. A friend and I would really like a couple of those belts, so if you're reading this, could you please travel back to the summer of 2003 and contact GREEN ANDY and give him at least two of them? We promise not to sell them or change the course of history. Thank you in advance.
