A construction foreman ordered one of his men to dig a hole eight metres deep.
After the job was done, the boss returned and explained an error had been made and the hole wouldn’t be needed. “Fill ‘er up,” he ordered the worker.
The worker did as he’d been told but he ran into a problem. He couldn’t get all the dirt packed back into the hole without leaving a mound on top. He went to the office and explained his problem.
“Honestly!” the foreman snorted. “The kind of help I get these days! There’s obviously only one thing to do. You’ll have to dig that hole deeper!”
