Same here! 8th grade math, I needed to boost my grade up to get an A. My teacher said if I memorized her poster on the wall of the pi digits, I would get enough extra cred points to bump it to an A-.Nothing too special or exotic, just 75 digits of pi. It is not completely useless; I use it to make my password sometime.
I know all the news you never knew that you knew you never needed to know. And I like saying that because people never catch all of it the first two times through.
