Until about a century ago, kings used to rule nations. As a symbol of their power and charisma, Kings had their heads engraved on the coins. Then kings died, when there was no head left over them. One of our kings tried to use whatever was left over his torso and came up with a bright idea. He made a pillar which had 4 lions sculpted over the top facing the four directions. Finally, after continued efforts, the emperors head (Her Majesty, The Queen’s, in our case) was replaced by the three lions. The fourth cat was let loose in the jungle and maybe that’s why all animals flocked to the front side of the pedestal from the hinds. Anyways, every animal was now facing outwards from the pillar, before the photograph of them was taken, to be punched on every coin from then on. The other side eventually came to be known as Tails, because there were no humans involved on the other side. Even today, some variants appear with a person’s face on their heads’ side and I wonder, “Did they really have Tails?”
Take a thin coin. Check if it’s unbiased. Toss it high in the air giving maximum rotations. Make a call, Heads or tails. Catch the coin, or let it reach the ground. Check whose wish has been granted. The winner then decides which option he would choose out of the few alternatives that he has. This method is suited only under able guidance, referees in most cases. What if there is not referee? Even worse, what if there is no coin?
Dry or wet? In villages, both the referees and coins are often missing and it can be very troublesome to decide who the toss winner is. This method comes directly from the ages of Flintstones. The coin is replaced by a piece of flat stone. Make one of its sides wet, often accomplished by spitting on to it, to make it an ideal substitute for a coin. Toss away to glory, and no one would run after you if you stole their stone. There are no restrictions on the size of the stone, no thickness constraints, as long as you can toss them in the air. Definitely an advantage over coins.
** The fourth lion is still absconding from the coins, please report if you find him. Save Tigers, their tongues have the best moisturizers for your face. Let them lick you. Don't poach them. Love them and they'll love you.
