I've stopped lurking for a minute, to say that this blond joke just keeps getting better the more you think about it.

If I'm not mistaken....

....there's no six digit version.

Seven digits: 3211000

Eight: 42101000

Nine: 521001000

So here's a pattern arising.

Ten of course is yours truly.

Eleven: 72100001000

The last digit would mean something like (0 1-digit representations of 10, e.g. X, as in ISBN numbers)

Twelve: 821000001000

Thirteen: 9210000001000

And what do we do with fourteen?

If we con't use X, since it's a kind of dummy place holder in our thinking about ten through thirteen and not a real digit, I think there is no answer to fourteen. What about higher numbers?

21200 is I think really interesting. It's the only five digit number that works, but not only is the whole number self- describing, the 1 which is the second digit refers to itself. It's forced to, because ot there weren't a 1 there would be 3 zeroes, therefore a three, therefore a 1. So the 1 is a kind of insulation of its place from having to be counted as anything but a 1. I wonder if there are other versions of this phenomenon.
