TWO MEN are out for a walk in the countryside. They find a well, and want to know how deep it is. So they drop a stone down. There’s no splash. They drop a rock, and listen – still no splash.
Then they find a millstone nearby, stand it up between them, and with a lot of effort roll it to the edge of the well. They push it in, and listen.
Suddenly a goat appears out of nowhere, rushing at top speed towards them. It bounds over their heads and disappears into the well.
A short time later a farmer comes along.
‘Have you seen my goat?’ he asks.
‘Well,’ says one of the men, ‘a goat just fell down that well.’
‘Can’t have been my goat,’ the farmer replies. ‘My goat was tied to a millstone.’
