A game, devilishly simple to play, but with enormous potential for mischief.

Extend your index finger at the same height as someone's cheek, and get them to turn their head, so that the extended finger connects - sometimes quite sharply - with the cheek. A simple: "what the hell is that?!!" can often be enough to get the intended recipient to look away, whereupon you place The Finger in anticipation of them turning their head back.

If the victim is not feeling jovial, you may find The Finger being countered with The Fist.
