No Fishing Bait

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 and 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.
