There was this leech...
So in a dark dense forest, on a pig's body there lived a leech. Over a period of time the leech got bigger and thicker by sucking the blood of the pig and started thinking as if he was a snake. One day the pig was bitten by a snake and died. A gang of Hyenas came and ate its' body. The leech got a chance and stuck to the Hyenas' body. The new blood gave him a fresh lease of life and strengthened his believes.
I am not sure what the motto of the story is, but surely is very funny.
