Ummm...How cool is that?!?

Don't ask questions, because my brain in summer mode is incapable of
teaching effectively (though I did give a little girl on the airplane
math help, as well as giving her a hard time for doing smart kid stuff
in the SUMMER)! However, like I have said before, I can't help being a
geek. So, enjoy the link, and tread lightly...your brain might explode
(especially if you click the 12,837,064 digit link)!
