Tortoise And The Fish

All fish were excited. What was the reason for their excitement? It was a worm tied to a string coming down.

"Guys, stay away from that. It's a bait. If you take a bite, you are done," the tortoise tried to warn the fish about the bait, which was slowly coming down. But the fish didn't listen to him. A fish took a bite, and that's it. He was stuck on the bait. The fish was lifted up. Nobody saw him again.
