A young man at this construction site was bragging that he could outdo anyone based on his strength. He especially made fun of one of the older workman. After several minutes, the older worker had enough. 
"Why don't you put your money where you mouth is?" he said. "I'll bet a week's wages that I can haul something in a wheelbarrow over to the other building that you won't be able to wheel back." 
"You're on, old man," the young man replied. "Let's see what you've got." 
The old man reached out and grabbed the wheelbarrow by the handles. Then nodding to the young man, he said with a smile, "All right. Get in."

Faraday on River Thames pollution

In 1855, a letter from Michael Faraday in The Times newspaper, London, described the polluted state of the River Thames he had observed on a boat trip: “The whole of the river was an opaque pale brown fluid. In order to test the degree of opacity, I ... dropped [pieces of card] into the water at every pier the boat came to; before they had sunk an inch below the surface they were indistinguishable, though the sun shone brightly at the time.”His words, he said, were no exaggeration, they were “the simple truth.” He asserted, “If there be sufficient authority to remove a putrescent pond from the neighbourhood of a few simple dwellings, surely the river which flows for so many miles through London ought not to be allowed to become a fermenting sewer.”[Image: 1855 Punch cartoon of Father Thames greeting Faraday.]
