Although this married couple enjoyed their luxury fishing boat together, it was the husband who was always behind the wheel operating the boat. He was concerned about what might happen in an emergency. So one day out on the lake he suddenly said to his wife, "Ok honey, this is a drill. Pretend that I am having a heart attack. You must get the boat safely to shore."
She was initially surprised and flustered, but she soon settled down and was able to safely drive the boat to shore.
Later that evening, the wife walked into the living room where her husband was watching television. She sat down next to him, grabbed the remote control, switched the channel, and said to him, "OK honey, this is a drill. Pretend I'm having a heart attack. You must set the table, cook dinner, and wash the dishes."

Centre-pivot irrigator

In 1952, a U.S. patent for a "Self-Propelled Sprinkling Irrigating Apparatus" was issued to Frank L. Zybach of Strasburg, Colorado (No. 2,604,359). A centre-pivoted pipe supported on a series of water-piston-powered wheels rotates and sprinkles water on the crops.A control system ensures that each wheel advances at the correct rate. This is the now-familiar centre-pivot machine that waters large circles of crops in those areas of a country which have limited rainfall but have a supply of surface or well water. It provides irrigation for large areas of even closely-spaced crops for which irrigation ditches are not practical and wasteful of water, or that would be expensive to supply with full coverage with stationary sprinklers.«[Image: a modern example showing the sprinkler pipe carried above a series of large wheels.]
