Legally change your name, first and last. For the rest of your life, you will constantly get twice as many credit card applications and other various junk mail, one piece for each name. I've seen this happen to several people.
My friend actually did something like this accidentally. He went by his middle name all of his life (it's a family tradition for some reason). When we were in middle school together the school accidentally had him listed twice in their computers. He also apparently got duplicates of his W2 forms a couple times.
I know this wasn't quite what you wanted, but it's the closest thing I could think of.
