761 - FLANK

Having completed the LAst check of the zonal details on the chart, Herbert went back to the workshop. It was time to start on the sculpture. He put the heavy plastic sheet into the clamp and he proceeded to cut into it. All was going well until one slash damaged a pressurised oil gland on the nearby machine and warm oil started spraying everywhere. He groaned; the disappointment made his mind go blank and he froze. Hearing the kerfuffle, Frank dashed in and attended to the machine, stemming the flow of oil. "Oh, thank you", said Herbert. "What's your name - I'll make you a special piece of artwork." "My name is Frank", he replied. "Did you say Flank", asked Herbert, who still had his ear protectors on. Frank pointed to his protectors and, once Herbert had removed them, he was able to correct what Herbert thought he'd heard. They laughed!
