I know of at least one place gives out free pie on Pi day if you can recite 100 digits of pi. (For each digit of pi you have memorized you get 1% off) Say a slice of pie is $3. Pi day comes around once a year. Assume you'll live for 60 more years, getting your free slice of pi every year, and the average inflation adjusted interest rate will be roughly 3%. Then the present value of memorizing the digits of pi will be $83.03. How long will it take you to memorize? How much are you getting paid hourly now?
