There's a fly flying 3 inches above the water

And there is a fish watching this. That fish thinks "if that fly would come down 3 inches, I could swim up and grab that fly."

Now there is a bear watching this. He sees what's going on and thinks to himself, "if that fly comes down 3 inches, that fish would swim up and get the fly and I could run out and get that fish."

Just then there is a hunter watching this. That hunter says to himself, "if that fly would come down 3 inches, the fish could swim up and eat that fly. Then that bear could run out and eat that fish and I could jump up and shoot that bear."

Now there is a mouse watching this. The mouse sees a cheese sandwich in the hunter's back pocket and thinks to himself, "if that fly would come down 3 inches, the fish would get the fly, the bear would run out and eat the fish, the hunter would jump up and shoot that bear and the cheese sandwich would fall out of his back pocket and I could scurry up and eat that sandwich."

Now there is a cat watching this. He thinks to himself, "If that fly would come down 3 inches...the fish would get the fly, the bear would get the fish, the hunter would jump up and shoot the bear, the mouse would scurry up and get the cheese sandwich and I could jump out and get that mouse."

Just then, the fly comes down 3 inches.

Just as planned, the fish swims up and gets the fly. The bear runs out and eats the fish. The hunter jumps up and shoots the bear and the cheese sandwich falls out of his back pocket. The mouse scurries up and gets the cheese sandwich and the cat jumps out after the mouse and misses and falls in the lake.

The moral of this story is: When the fly comes down 3 inches, pussy gets wet.
