One spring day, a fish was swimming about a foot below the surface of a lake and saw a fly hovering just out of striking distance.
The fish said to itself, "If that fly comes six inches closer, I'll jump up and have myself a meal."
Just then, a bear on the shore of the lake looked up and said to itself, "If that fly gets any closer to that fish, the fish will jump up, and I'll catch the fish and have myself a meal."

As luck would have it, a hunter saw what was happening. He thought to himself, "If that fly moves closer to the fish, the fish will jump, the bear will lean over to grab the fish, and I'll shoot the bear."

Just then, a rat was standing behind the hunter saying to itself, "If the fly moves closer to the fish, the fish will jump, the bear will lean over to grab the fish, the hunter will lean over to shoot the bear, and I'll grab the sandwich from the back pocket of the hunter."

However, unbeknownst to the rat, a cat was observing everything and thinking, "If that fly moves closer to the fish, the fish will jump, the bear will grab the fish, the hunter will shoot the bear, the rat will grab the sandwich, and I'll snatch the rat."

At that very moment, the fly dropped a few inches, the fish grabbed the fly, the bear grabbed the fish, the hunter shot the bear, the rat grabbed the sandwich, the cat jumped, missed the rat and landed in the lake.

The moral of this story is:
A lot has to happen before the pussy gets wet.
