Just learn the first few digits. Supposedly 40-something digits is all you need for a circle the size of the universe, to the accuracy of a proton.

Link? I strongly doubt that. How big is the universe?
Actually that's not too far off.

The universe is approximately 10^10 lightyears across, which is around 10^26 metres.
A proton is approximately 10^-15 metres across, which means the universe is about 10^41 protons across so Pi to 40 decimal places would give the diameter of the universe to an accuracy of around 10 protons given the circumference.

Good, I didn't feel like finding a link ;)

I take a piece of string and run in across a circle to make sure its the length of the diameter. Then I try to line the string around the edge of a circle and see how many strings the circle needs to go around. you need a really big circle and a really accurate ruler :D
