Oi tink that there should be a fourth, fifth and sixth medal as well as the usual three, a fourth and fifth sixth medal specially presented to the winners who muck about in water.
Swimmers divers, water poloists and for the event where women competitors wave their legs about upside down in the pool, to be presented, with the winner getting a magnesium medal, second place an aluminium and for third place a zinc medal.
For the sea water bods a zinc medal for the winner and aluminium second and magnesium for third place.
They receive a mixture of medals in case they swap their favoured sport from fresh water to salt water or visa versa.
The idea is to prevent the competitors getting pitted all over by galvanic reaction and spoiling their looks.
