"A joke moves in two dimensions. First it moves in a logical dimension. You can conceive it. If the joke goes on logically to the very end, it will cease to be a joke; there will be no laughter. So suddenly the joke takes a turn and becomes so illogical that you cannot conceive it. And when the joke takes a turn and the result becomes illogical; then the expectation, the tension that was created in you, suddenly explodes. You relax. Laughter comes out.
Laughter is the relaxation. But tension is first needed. A story creates expectation, suspense and tension. You start feeling the crescendo. Now the crescendo will come. Something is going to happen. Your backbone is straight like that of a yogi. You have no more thoughts in the mind. The whole being is just waiting. All the energy is moving toward the conclusion. Suddenly something happens which the mind could not think of. Something absurd happens ??? something illogical, irrational.
The end is such that it was impossible for logic to think about it. And you explode. The whole energy that had become tense inside you suddenly gets relaxed. Laughter comes out through this relaxation. ???Man is bored. Hence he needs laughter. The more bored, the more laughter he will need. Otherwise, he cannot exist.
Thirdly, it has to be understood that there are three types of laughter. The first is when you laugh at someone else. This is the meanest, the lowest, the most ordinary and vulgar when you laugh at the expense of somebody else. This is the violent, the aggressive, the insulting type. Deep down this laughter there is always a feeling of revenge."
