The Crow and the Oyster

A crow found an oyster on the seashore. He tried to break its shell, but it wouldn't open. He then threw a stone at the oyster, but nothing happened.

"My friend, the oyster won’t open that way," said a cunning crow to the first. "Take my advice: fly high into the sky with the oyster in your beak and drop it onto a rock. Only then will it break."

The first crow liked the suggestion and decided to follow it. He picked up the oyster in his beak, flew high, and dropped it. The shell broke instantly, but the cunning crow immediately swooped down, grabbed it, and ate the meat inside. When the first crow flew down to where the oyster had landed, all he found was the empty, broken shell.

Beware of those who offer advice with hidden motives.
