In this article, we explain the relationship between laughter and the effects of human thinking, which includes theorizing and thus predicting world events. Our hypothesis is that human beings theorising acts are about to escape or control the pains of life in order to make the world events predictable. But predictability is like a double-edged sword, because on the one hand it can eliminate human pains, and on the other hand it leads to monotony, habit, boredom and daily life. In this regard, laughter opposes uniformity, monotony, and predictability, calls for the emergence of undefined and unpredictable behaviors to save mankind from the boredom and numbness caused by thinking, theorizing and predictability. Throw him a world with new rules that govern the relationships between its events and convey the joy of breathing in a fresh and undiscovered universe. Laughter introduces a new world that, like narcotics, is full of joy and forgetfulness.
