Back in the late 90's me and a friend were memorizing PI just for fun. I got to 300 digits. Based on how long it took me to recite those 300 digits, we estimated that the world record holder at that time spent about 16 hours just reciting the numbers. I can't imagine the time they must have put into memorizing it.
