I'm not impressed with this video; Carmonk can recite 500 Pi digits in less than a minute without error... I've even seen him vary the pitch of each digit to mimic the theme song of Rain Man
I was thinking you could just get the first 20 or so right and start making up numbers from there, but then I realized the Youtube Nerd patrol would find you out and 'recite numbers' you to an early grave.
