There are some bizarre playground games for two that involve pain. Well known ones such as Feet Stamping, Slapsies and Knuckles and lesser known such as Extreme Rock Paper Scissors. But, there is one that understandably and thankfully never played today: Slapheads.
Slapheads is like the human equivalent of the summer fayre game of Hit the Rat ( a 'rat' is dropped through a drainpipe and the player has to hit it with a baseball bat when it emerges) Here, one person must hold his hands, palms facing inwards, a set distance apart (2 feet or so). The other must now bob his head down between the hands and avoid being slapped in the head. To trial this game I have just played a session with Mrs Blister and it is brilliant fun. Whether it's through fear of reprisals or slowness of reactions the bobber often wins and the slapee is left slapping thin air.
I suppose if this marvellous game were to take off today then the wearing of a safety helmet would be the only update required. Encouraging children to play old fashioned games to help in the fight against obesity is all well and good but not at the expense of a perforated ear drum.
