Just like King Canute I am unable to persuade the tide to Get Back (from the Beatles' album, Let It Be, 1969).
Canute was the first Viking king of all England and later became king of England, Denmark, of Norway and part of Sweden. His courtiers kow-towed to him and flattered him to extremes; they even said, 'You are so great that even the tides would obey you.' To prove them wrong, Canute had his throne carried to the seashore and sat there commanding the tide to 'get back'. Of course it didn't and Canute said, "Let all men know how empty and worthless is the power of kings. For there is none worthy of the name but God, whom heaven, earth and sea obey".
