A fly drops 6 inches.

There's a fly hovering above a lake just out of the reach of a fish.
The fly drops 6 inches so the fish jumped out of the water and eats it.
Unfortunately there is a bear waiting for that fish and the bear snags the fish.
Across the lake on the shore there's a hunter who is aiming his rifle at that bear.
He misses because a mouse is eating his crackers and that little noise was enough to ruin his aim.
The cat that has been stalking the mouse then tries to pounce on the mouse but misses and ends up in the water.

Moral of the story: When the fly drops 6 inches the pussy is sure to get wet.
