When it comes to creative writing or speaking, there's something rotten in Denmark: Bernard Levin said it best with the following -
"If you cannot understand my argument, and declare, "It's Greek to me", you are quoting Shakespeare; if you recall your salad days, you are quoting Shakespeare; if you act more in sorrow than in anger, if your wish is father to the thought, if you have ever refused to budge an inch or suffered from green-eyed jealousy, if you have played fast and loose, if you have been tongue-tied, a tower of strength, hoodwinked or in a pickle, if you have knitted your brows, made a virtue of necessity, insisted on fair play, slept not one wink, stood on ceremony, danced attendance (on your lord and master), laughed yourself into stitches, had short shrift, cold comfort or too much of a good thing, if you have seen better days or lived in a fool's paradise - why, be that as it may, the more fool you, for it is a foregone conclusion that you are (as luck would have it) quoting Shakespeare.
If you clear out bag and baggage, if you think it is high time and that that is the long and short of it, if you believe that the game is up and that truth will out even if it involves your own flesh and blood, if you lie low till the crack of doom because you suspect foul play, if you have your teeth set on edge (at one fell swoop); without rhyme or reason, then to give the devil his due - if the truth were known (for surely you have a tongue in your head) you are quoting Shakespeare.
Even if you bid me good riddance and send me packing, if you wish I was dead as a doornail, if you think I am an eyesore, a laughing stock, the devil incarnate, a stony-hearted villain, bloody-minded or a blinking idiot, then - By Jove! O Lord! Tut, Tut!; For goodness' sake!; What the dickens! But me no buts - It is all one to me
FOR YOU ARE QUOTING SHAKESPEARE"
