A certain gum company (Bazooka) promised me that by the age of 21, I'll reach the moon (part of the product included a portion that "foretold your future"). Since 21 is sadly well behind me, I'm currently suing them for false advertisement (just kidding ).
But I just stumbled upon the following site, that will at least let me get my name to the moon. NASA is sending an LRO (Lunar Reconnaissance Orbiter) to the moon, and if you submit your name by 6/27/08, it will be included in a list that will be left there.
Go to this site to read more about the initiative, and here to add your name. You'll end up with this certificate:
Just don't come to me when aliens find your name on the moon and come looking for you by name .
