One of my brothers was into role playing games and had a collection of dice, including the normal cubical 6 sided, a tetrahedral 4 sided, a penny he used as a 2 sided, various other shaped and numbered ones, even a 100 sided that looked like a golf ball, he joked that he had a 1 sided one once, but it landed face down and disappeared into another dimension.
