So, in the late 90's I went to a goth convention in New Orleans, where my wife met a time traveller named "Butterfly". I saw her talking to a weird looking guy, and swung by to see if she needed help, but she had that "oh this is going to be a great story" look on her face and kind of shooed me away. Later, she told me he had claimed to be from the future. He made some predictions:<p>- there would be a war in Iraq, but it was not actually as big as the one that happened later<p>- after the Big War, there was a disease that forced everyone to live belowground<p>- he had a computer chip in his hand<p>- he had a son in the future named Gandalf<p>This all seemed pretty wacky, if harmless. My wife enjoyed relating it all in our Yahoo Groups email group. Then, in the next few years:<p>- the implanting of computer chips in pets became commonplace<p>- we started hearing about new viruses every few years<p>- we went to war in Iraq<p>- Lord of the Rings movies came out, which made it more likely someone would name their son "Gandalf"<p>So, I asked my wife, "what else did that guy say would happen?"<p>She said, "I don't remember it all now, but I put a really detailed list in my email to the Yahoo Group."<p>So, we look in the Yahoo Groups history, and...that month was missing from the history.<p>Oh, well. If he had said anything more significant than a global pandemic and WW3, I assume I would have remembered it.
