One afternoon, a fox was walking through the forest and spotted a bunch of grapes hanging from a lofty branch. "Just the thing to quench my thirst," said the fox.
Taking a few steps back, the fox jumped and just missed the hanging grapes. Again, the fox took a few paces back and tried to reach them, but still failed.
Finally, giving up, the fox turned up his nose and said, "They're probably sour anyway." Then he walked away.
