DNA double helix

In 1953, the journal Nature published a paper with this date from Francis Crick and James Watson, titled Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid, in which they described a double helix structure for DNA. The diagram published with the caper was captioned, "The figure is purely diagrammatic. The two ribbons symbolize the phosphate-sugar chains, and the horizontal rods the pairs of bases holding the chains together. The vertical line marks the fibre axis."[Image: diagram as published in Nature paper.]

A magician was working on a cruise ship in the Caribbean. The audience would be different each week, so the magician allowed himself to do the same tricks over and over again. There was only one problem: The captain's parrot saw the shows every week and began to understand what the magician does in every trick.
Once he understood that, he started shouting in the middle of the show: Look, it's not the same hat. Look, he is hiding the flowers under the table! Hey, why are all the cards the Ace of Spades?
The magician was furious but couldn't do anything, it was the captain's parrot after all. One day the ship had an accident and sunk. The magician found himself on a piece of wood, in the middle of the ocean, with the parrot of course. They stared at each other with hate, but did not utter a word. This went on for a day, and another, and another.
After a week the parrot finally said: OK. I give up. What'd you do with the boat ?
