A father shark teaches his kid how to hunt people:

"When you see a human, you approach to about 30ft from him, make sure he sees you and then you swim a couple of circles around him. Then you get closer to about 10ft, and again you swim a few circles around him. Then you come really close to him, even touch him, you wait one minute and then, well, you eat him."

"But why can't I just get him and eat him?" asks the little shark.

"You can do that, too, if you don't mind eating his shit."
