Just start teaching the next generation of kids that the greatest day in the world is on February 18th 2012. We must never mention why its the greatest day so it builds up a lot of curiosity to why its the greatest day.
Now hundreds of years in the future when the time machine gets invented someone is going to take a time machine to the day February 18th 2012 to see the reason why its the greatest day.Once they arrive I will be there ready to jump them, steal the time machine and claim it to be my invention.
