Urinal Cakes are small, often round, blue lumps that sit in urinals.
Despite the name, they are not edible and problably shouldn't be eaten before they are placed in a urinal, they certainly shouldn't after.

Players: 1 upwards

Location: A public house, or public convienience with one long urinal. The game can not be played in lavatories with individual urinals.

Object: To move the urinal cake from its random starting position to the drain.

Play begins when a group of (male) friends enter a public house and the beer ¹ begins to flow. Convention dictates that unlike women, men should enter the lavatory one at a time - whenever needed. A player may take as many or as few turns as required. The Cake may only be moved by the force of piddle. Objetcs may not be added to the guttering to speed up or hamper the movement of the cake. The winner is the player who manages to move the cake onto the drainage hole in the urinal.
