[Damocles]

An elderly Irish businessman buys a large house. The house is situated on a cliff overlooking the sea. One evening, the old gentleman is out for his usual walk before going to bed. The evening is a very blustery one. He ventures a little too close to the cliff's edge, loses his footing and falls over the brink.
Fortunately, he is able to grasp a very slender sapling that is growing out of the cliff, which stops his fall. The old gentleman hangs there for a few moments, terribly shaken. Eventually he calls out, "Is there anybody there?"
At once a great voice seem to fill the whole of the firmament. It comes out of the clouds, out of the sea and out of the cliff itself. It says in measured tones, "There is always someone up here, my son. All that you need to do is release your hold upon that small tree and you will descend safely to the shore below."
The old gentleman considers this for a moment and takes a look down at the jagged rocks 200ft below him. Then he looks up again and says, "Is there anybody else up there?"
