There was a fly looking at some food in a river. The fly thought, "If I go down, I can get the food!"
There was a fish looking at the fly. The fish thought, "If the fly goes down to get the food, I can get the fly!"
There was a bear looking at the fish. The bear thought, "If the fly goes down to get the food, and that fish comes up to get the fly, I can get the fish!"
There was a man looking at the bear. The man thought, "If the fly goes down to get the food, the fish comes up to get the fly, and the bear gets the fish, I can shoot the bear!"
There was a mouse looking at the man. The mouse thought, "If the fly goes down to get the food, the fish comes up to get the fly, the bear gets the fish, and the man shoots the bear, I can get the man's sandwich!"
There was a cat looking at the mouse. The cat thought, "If the fly goes down to get the food, the fish comes up to get the fly, the bear gets the fish, the man shoots the bear, and the mouse gets the sandwich, I can get the mouse!"
So the fly goes down to get the food. The fish comes up and gets the fly. The bear swipes his mighty paw and gets the fish. The man shoots the bear. The mouse runs for the man's sandwich. The cat lunges for the mouse, misses, and falls in the river.
