even I think this is cool

and I'm not even a great big nerdy nerd like some people.

This site (that I found linked on BoingBoing.net) has a list of numbers from 1 to 9999 and a reason it's special.

For instance, did you know that;

27 is the largest number that is the sum of the digits of its cube.


and

2 is the only even prime.

and

30 is the largest number with the property that all smaller numbers relatively prime to it are prime.
