A man who does not know to swim, was shouting for help in the middle of a River. Some good hearted people rushed to the spot and pulled him out of the danger.
They all gave him first aid treatment and he was able to recover.
They : Why did you go to that spot , man?
He : I wished to cross the River, Sir.
They : Dont you know that it is very deep in the middle?
He : Yes Sir.
They : You dont know swimming. You also know it is very deep in the middle. Then why the hell you tried to cross?
He : I enquired a passerby, what the depth of the River is. He said that at the 1st point it is 1 foot, 2nd point 3 feet, 3rd point 7 feet, 4th point 10 feet, 5th point 7 feet, 6th point 3 feet and at 7th point 1 foot. On an average it is only about 4 feet and 7 inches, where as I am 6 feet tall. As I am taller by 1 foot 5 inches than the average, I thought I can very easily cross the River, Sir.
