Having arrived at the edge of the river

Having arrived at the edge of the river, the fisherman soon realized he had forgotten to bring any bait. Just then he happened to see a little snake passing by who had caught a worm. The fisherman snatched up the snake and robbed him of his worm. Feeling sorry for the little snake with no lunch, he snatched him up again and poured a little beer down his throat. Then he went about his fishing.
An hour or so later the fisherman felt a tug at his pant leg. Looking down, he saw the same snake with three more worms in his mouth...

Really really funny jokes
