The History of the Middle Finger & "Fuck You"

This may be the most often used word in the English language, probably after the word "the". But how many of us know the origin of the words "fuck you". Culture and history are intertwined and can explain how things are the way they are today. Teenagers reading this can share the origin of "fuck you" with their parents the next time they get reprimanded for using the phrase - once you can explain the history to your parents, its not so bad. Somehow I think the story is true because I have read and heard many times before about 'giving him the bird' - which I thought was silly although that had overt nasty overtones. Now it all makes sense.
Well, now......here’s something I never knew before, and now that I know it, I feel compelled to send it on to my more intelligent friends in the hope that they, too, will feel edified. Isn't history more fun when you know something about it?

Before the Battle of Agincourt in 1415, the French, anticipating victory over the English, proposed to cut off the middle finger of all captured English soldiers. Without the middle finger, it would be impossible to draw the renowned English longbow; and therefore, they would be incapable of fighting in the future. This famous English longbow was made of the native English Yew tree, and the act of drawing the longbow was known as 'plucking the yew' (or 'pluck yew').

Much to the bewilderment of the French, the English won a major upset and began mocking the French by waving their middle fingers at the defeated French, saying, “See, we can still pluck yew!” Since 'pluck yew' is rather difficult to say, the difficult consonant cluster at the beginning has gradually changed to a labio-dentals fricative F', and thus the words often used in conjunction with the one-finger-salute! It is also because of the pheasant feathers on the arrows used with the longbow that the symbolic gesture is known as 'giving the bird.'
