It goes something like this...

3.141592653589793238462643383279502884196

Explanation:

I did take an interest in memorising pi when I was much younger, but did not bother to memorise it past about 40 decimal places.

My method was to memorise groups of about 5 or 6 digits at a time, making sure I remembered them, before memorising the next group a day or two later.

It is not particularly useful to know pi to this accuracy, but I guess it makes a little party trick.

If you do not really want to memorise a whole load of digits, then just memorise 355/113 ~~ 3.1415929 which is an excellent approximation to pi discovered by a Chinese mathematician about 1500 years ago.
