As to how he did it (Score 0)

Sorry, I didn't credit the person above to mention goroawase. Anyway, there are many ways to pronounce the numbers in Japanese and many more can be assumed, so it's easy to just remember the story and recite it. Just for fun, I took a minute to do an example: 3.14159265358979323846 which could be pronounced "san hito yon ichi go kuu - futarou gomi, itsuya kyuushichi, kumi futami. hashi roku." which would translate literally as "3 people eat 4 strawberries - Futaro Gomi, Itsuya Kyuushichi, Kumi Futami (all legitimate Japanese personal names). There are 6 chopsticks."
