Cottle, in his life of Coleridge, relates the following amusing incident:–‘I led my horse to the stable, where a sad perplexity arose. I removed the harness without difficulty; but, after many strenuous attempts, I could not remove the collar. In despair, I called for assistance, when Mr. Wordsworth brought his ingenuity into exercise; but, after several unsuccessful efforts, he relinquished the achievement as a thing altogether impracticable. Mr. Coleridge now tried his hand, but showed no more skill than his predecessor; for, after twisting the poor horse’s neck almost to strangulation, and the great danger of his eyes, he gave up the useless task, pronouncing that the horse’s head must have grown since the collar was put on; for he said, ‘it was a downright impossibility for such a huge os frontis to pass through so narrow an aperture.’ Just at this instant, a servant-girl came near, and understanding the cause of our consternation, ‘Ha! master,’ said she, ‘you don’t go about the work in the right way: you should do like this,’ when, turning the collar upside down, she slipped it off in a moment, to our great humiliation and wonderment, each satisfied afresh that there were heights of knowledge in the world to which we had not yet attained.

In 1855 American publisher James T. Fields made the mistake of taking William Thackeray to a dull scientific lecture:

During his second visit to Boston I was asked to invite him to attend an evening meeting of a scientific club, which was to be held at the house of a distinguished member. I was very reluctant to ask him to be present, for I knew he could be easily bored, and I was fearful that a prosy essay or geological speech might ensue, and I knew he would be exasperated with me, even although I were the innocent cause of his affliction. My worst fears were realized. We had hardly got seated, before a dull, bilious-looking old gentleman rose, and applied his auger with such pertinacity that we were all bored nearly to distraction. I dared not look at Thackeray, but I felt that his eye was upon me. My distress may be imagined, when he got up quite deliberately from the prominent place where a chair had been set for him, and made his exit very noiselessly into a small anteroom leading into the larger room, and in which no one was sitting. The small apartment was dimly lighted, but he knew that I knew he was there. Then commenced a series of pantomimic feats impossible to describe adequately. He threw an imaginary person (myself, of course) upon the floor, and proceeded to stab him several times with a paper-folder which he caught up for the purpose. After disposing of his victim in this way, he was not satisfied, for the dull lecture still went on in the other room, and he fired an imaginary revolver several times at an imaginary head. Still, the droning speaker proceeded with his frozen subject (it was something about the Arctic regions, if I remember rightly), and now began the greatest pantomimic scene of all, namely, murder by poison, after the manner in which the player King is disposed of in Hamlet. Thackeray had found a small phial on the mantel-shelf, and out of it he proceeded to pour the imaginary ‘juice of cursed hebenon’ into the imaginary porches of somebody’s ears. The whole thing was inimitably done, and I hoped nobody saw it but myself; but years afterwards a ponderous, fat-witted young man put the question squarely to me: ‘What was the matter with Mr. Thackeray that night the club met at M—-‘s house?’
