because it has a k in it.â
âThe letter k is funny, is it?â
âNot in and of itself. Itâs the k sound that prompts amusement. When a mouth forms the k in any word, it widens into a grin, subconsciously making those observing this smile along. Many words that are endowed with the k factor are among the most amusing in the English language. Think of it: knickers, scuttlebutt, spelunking.â
âI have to admit, I always have to conceal a smirk when introduced to a Kenneth.â
I studied Holmesâs tired face. âWould you like me to make you something to eat? I canât remember the last time I saw you indulge in foodstuffs.â
âThank you, Watson, that is very considerate.â
âWhat would you like?â
âItâs obvious.â He smiled. âKippers, of course!â
The next day, as I was going over some particularly intriguing anatomical texts, Holmes barreled out of his room.
âWatson! Knock, knock.â
âAh! Ha ha â¦yes, very funny, Holmes.â
âWhat is?â
âYour two k sounds. Yes, quite amusing.â
âNo, no, this is a different thing altogether. Knock, knock.â
I stared at him.
âKnock, knock,â Holmes repeated.
âWhy do you keep saying âKnock, knock?ââ
âItâs something I have just invented. Well, to be truthful, I borrowed it from Shakespeare. The Porterâ¦from Macbeth . Are you familiar with it?â
âYes, Holmes, I am. Iâm not illiterate, you know. I have read plays and books. You may have seen me with a newspaper at times.â
âAll right, all right. No need to get your dander up. The Porter in the Scottish play pretends to be the porter to the gates of hell welcoming sinners of different professions. All follow the pattern of âKnock, knock,â to which comes the reply âWhoâs there?â Then comes the joke. In the play it was a monologue, but I have devised it so that the audience can become part of the fun.â
âHow will they know to say âWhoâs there?ââ
Holmes seemed nonplussed. âWhat?â
âHow,â I said, unconsciously slowing down as if talking to a Frenchman or a somewhat addled cocker spaniel, âwill the audience know to say âWhoâs there?ââ
âI shall tell them. That does not matter at the moment. I am trying to work the concept to see if the format is successful.â
âAll right. Whoâs there?â
âWait for the set-up, will you? Knock, knock.â
âYes?â
âNot âyes.â âWhoâs there?â Letâs start again, shall we?â Holmes sighed loudly. âKnock, knock.â
âWhoâs there?â I said.
ââTis I, Sherlock Holmes. Donât you recognize me?â
I stood stock-still, not knowing how to respond. Holmes, too, seemed a little uncertain.
âHmm,â he said. âThereâs something missingâ¦but what? What? Of course! Thereâs no familiarity with the concept, so there can be no deconstruction at this particularâ¦hmm.â He trailed off, lost in thought. âWatson, after I say who is at the door, repeat the name I give you, adding the word âwho.ââ
âAll right, Holmes.â
âKnock, knock.â
âWhoâs there?â
âSherlock.â
âSherlock who?â
Affecting a perfect Irish accent, Holmes replied, âSure, lock the door so I canât get in.â
I laughed. Heaven help me, I laughed. I have never seen Holmesâs face so lit up as when he heard that laugh. It worried me.
And so it was for the days leading up to Holmesâs debut as a standing up comedian. Just as I was growing accustomed to his prolonged absences, he would launch himself from his study talking about the science of eliciting laughter. If you have never had to sit through such a lecture, I can tell you it is
