Psalm 23
A man was always thinking up ways of making easy money and one day he thought he was on to a certainty. He taught his parrot to say the 23rd Psalm and then took it down the local pub.
“I bet anyone $10 my parrot can recite the 23rd Psalm from beginning to end,” he said.
Quite a lot of interest was shown and a pile of money quickly went down on the bar.
“Go on then, parrot, recite the psalm.”
Sadly the parrot remained completely dumb and eventually the man took it home, having lost quite a lot of money.
“Why the bloody hell didn’t you do as I taught you, you scrawny old bird?”
“Now hold on,” said the parrot. “Think what the odds will be tomorrow when we go back.”
