A climber fell off a cliff,...........................

and, as he tumbled down, he caught hold of a small branch. "Help! Is there anybody up there?" he shouted.
A majestic voice boomed through the gorge:
"I will help you, my son, but first you must have faith in me."
"Yes, yes, I trust you!", cried the man.
"Let go of the branch", boomed the voice.
There was a long pause, and the man shouted up again, "Is there anybody else up there?"
