Many years ago a group of friends used to have "dice evenings", based on the book The Dice Man by Luke Rhinehart - http://en.wikipedia.org/wiki/The_Dice_Man
We'd decide what we'd wear, what pubs we'd visit and what we'd do when we got there by the roll of a dice. My "dice name" was Josef Sneff and now Mr Sneff is the name I use for various online activities, including this blog - http://mrsneff.wordpress.com/
