For pi day at my school we had a competition to memorize the most digits of pi. Whoever won got a whole pie to themselves. The first year one of my best friends memorized 314 digits of pi, then the next year he memorized 628 digits and his goal for senior year was 1000. Unfortunately he didn't have any time to memorize it with all the school work and such. Anyways he still won that year, by just memory from the previous years memorization.
I've honestly never tried to learn them, never even remember reading pi written out, but this past year (my senior year) our math teacher asked if any of us would like to try to recite it so I did and got 33 right, I've tried a few times since then and got them correct.
