All you do is put a small blob of Marmite somewhere upon your body. Then your partner has to guess mole or marmite. A quick lick will soon reveal whether they are correct or not.
A more hardcore variation of this game is "Flakey Skin or Corny Flake". (Luka's Top Tip: cornflakes stick to the skin well if you soak them in milk first.)
