Heh. People used to spontaneously call me that when I was a kid (due to my name "Randall Randall" rather than my size, I expect), and it's way easier to google for. :)
Curious if you've read Catch-22. One of my favorite characters in the book was called "Major Major" (and of course his rank was Major). At some point they managed to get a 4th one on the end too.
I'm not sure if that's cruelty or awesome on the part of your parents. I'm leaning towards awesome.
