Mmmmmmm, Pi!

So here's a dude over in Japan who went for a Guinness World Record by memorizing and reciting pi to 100,000 decimal places: "3.141592653589793..."

Hunh. Back when I was in high school, budding geek that I was, I had pi memorized to 120 decimal places, of which I can still regurgitate the first 30 or so today. I also had e memorized to a good many decimal places.

I understand this sort of thing is easier in Japanese, where the names of numbers can be formed into mnemonic plays on words which can then be strung together into a story.
