When Noah's ark had finally come to a rest on top of mount Ararat, and when the waters had receded, Noah and his family - along with all the animals - left the ark, and God told them to go forth and be fruitful . nd re-populate the Earth.
Noah dispatched the animals with the instructions to go out and multiply. Soon there were baby lions and tigers and sheep and goats and frogs and every other sort of animal... except the adders. The adders refused to multiply, they would only add.
And Noah fearing the wrath of God who had told him to make ALL the animals multiply called his family together and explained the problem.
Noah's oldest son Sham was a smart kid who had an idea. He took the two disobedient snakes and locked them in the woodshed.
Two weeks later they came back and opened the woodshed door and out slivered the snakes followed by 20 baby adders. Noah was ecstatically happy.
"Sham my Son, how did you do this? Before you put them into the wood shed the adders would only add. Now look at them, they have multiplied. Its a miracle!"
"No father its not a miracle, just maths".
"I got them to use logs!"
