Fisherman Threw diamond in the river

Once a fisherman got up very early on a Sunday morning.
Since it was very dark, He decided to pass time.
He found a sack full of little pebbles.
He began tossing them into the river high and far.
Atlast when he had only one pebble left, The sun rose.
He saw the pebble, he was holding and It was a diamond.
He then realized that, He had just thrown a sackful of diamonds.

NEVER Get up so early on a Sunday morning.
