Pi = happiness. I know the first 100 digits or so, don't ask me why I have no life. I memorized ~50 in study hall one day because I had nothing to do, then got another 50 over the course of a few days at home. I have the first 8 million on my hard drive somewhere, but thanks for the link. And some supercomputer in Japan calculated it to 51 billion. I want that machine.
