His schoolfellow and friend, Dr. Taylor, told me a pleasant anecdote of Johnson's triumphing over his pupil David Garrick. When that great actor had played some little time at Goodman's fields, Johnson and Taylor went to see him perform, and afterwards passed the evening at a tavern with him and old Giffard. Johnson, who was ever depreciating stage-players, after censuring some mistakes in emphasis which Garrick had committed in the course of that night's acting, said, 'The players, Sir, have got a kind of rant, with which they run on, without any regard either to accent or emphasis.' Both Garrick and Giffard were offended at this sarcasm, and endeavoured to refute it; upon which Johnson rejoined, 'Well now, I'll give you something to speak, with which you are little acquainted, and then we shall see how just my observation is. That shall be the criterion. Let me hear you repeat the ninth Commandment, "Thou shalt not bear false witness against thy neighbour."' Both tried at it, said Dr. Taylor, and both mistook the emphasis, which should be upon not and false witness. Johnson put them right, and enjoyed his victory with great glee.
