Mediocrity knows nothing higher than itself; but talent instantly recognizes genius. You see, but you do not observe. The distinction is clear. The world is full of obvious things which nobody by any chance ever observes. I am the most incurably lazy devil that ever stood in shoe leather Is there any point to which you would wish to draw my attention? To the curious incident of the dog in the night-time. The dog did nothing in the night-time. That was the curious incident You will not apply my precept. How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth? We know that he did not come through the door, the window, or the chimney. We also know that he could not have been concealed in the room, as there is no concealment possible. When, then, did he come? 
I've opened a door here that I regret. Bad news. Andy Griffith turned us down. He didn't like his trailer. I'm afraid I just blue myself. Whoa, this guy's straight? 

How did your brain even learn human speech? Man walks down the street in a hat like that, you know he's not afraid of anything. 

Education never ends, Watson. It is a series of lessons, with the greatest for the last. I have always held, too, that pistol practice should be distinctly an open-air pastime; and when Holmes, in one of his queer humours, would sit in an armchair with his hair-trigger and a hundred Boxer cartridges and proceed to adorn the opposite wall with a patriotic V.R. done in bullet pocks, I felt strongly that neither the atmosphere nor the appearance of our room was improved by it. 

Elementary, my dear Watson. You will not apply my precept. How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth? We know that he did not come through the door, the window, or the chimney. We also know that he could not have been concealed in the room, as there is no concealment possible. When, then, did he come? Man, or at least criminal man, has lost all enterprise and originality. As to my own little practice, it seems to be degenerating into an agency for recovering lost lead pencils and giving advice to young ladies from boarding-schools. I must apologize for calling so late, and I must further beg you to be so unconventional as to allow me to leave your house presently by scrambling over your back garden wall. The world is full of obvious things which nobody by any chance ever observes. Come, Watson, come! The game is afoot. Not a word! Into your clothes and come! I am the most incurably lazy devil that ever stood in shoe leather My name is Sherlock Holmes.  It is my business to know what other people don't know. Show Holmes a drop of water and he would deduce the existence of the Atlantic. Show it to me and I would look for a tap. That was the difference between us. You see, but you do not observe. The distinction is clear.
