Yeah...I'm full of it (useless information, that is).

My birthday wasn't found, qwerty. So I changed a few numbers and then it found it....but then it's not my birthday, now, is it???

I have a great explanation of it in one of my books (way too many to go look through to find, though), but this less glamorous explanation will do. Squaring the circle
