Ever wonder why jokes make you laugh? Have you ever sat and watched a Woody Allen movie and been reduced to tears over something that you can only say is nonsense? Jokes seem to cut into something inside us, a reaction which we dearly welcome but know so little about. During this bout of pleasure there is an element of being out of control as if it hits on some part of us which we can't be readily seen. The title of Freud's thesis on jokes - Jokes and their relation to the unconscious - gives away what that unseen element is: the unconscious. In this essay I will move through a number of diverse ideas but all of them will be subsumed under the psychoanalytic heading of 'how do jokes work?' This essay doesn't attempt to answer every question on the unconscious and jokes. Instead I hope to give a good read through waters that have not been thoroughly charted. F or it is extraordinary that a phenomenon such as laughter which none of can do without is so scarcely written about. The theme of this work is that sexuality is at the heart of joking. I begin with it and I end with it. It might have been enjoyable to write about nothing else. Alas, that was not possible for as I have mentioned there is a dearth of material. I have instead brought in other ideas, all relevant but maybe not as beautifully radical. I hope the reader will come to the conclusion that although not every question that immediately comes to the surface is answered, this work does however leave you with some ideas and a set of new questions that are somewhat closer to the heart of joking.
