Empty swimming pool

A very wealthy entrepreneur named John retired to the countryside. On one of his long walks, he passed a Mental Institution, and behind the chain link fence, he saw the patients fighting ferociously with each other.

Hailing a man standing close to the fence, John asked what was going on.

The man replied, "This happens every day; there's nothing else to do."

So John went to see the director and offered to install a swimming pool at his expense. The director was very happy with the offer and accepted immediately.

Ten days later, John received a phone call from the director, requesting his presence the following day for the grand opening. Pleased, John accepted. He than decided to take a stroll out to the Institution to see how well the pool had been built.

As he approached the fence, he heard laughing and exited voices. A few yards later, he had a full view of a beautiful pool, complete with high tower diving boards, for which the patients were lining up to do cannonballs and swan dives.

Calling the same man at the fence, John said, "You guys like this, huh? I see no more fighting, isn't this fun?"

The man replied, "Sure is, Mister, but tomorrow it'll be even more fun when they put the water in it."
