According to Osho, humor clusters around certain cultures because it mirrors their lived personality. Jews, earthy and at ease with ordinariness, cultivated rich, self-mocking wit—humor as survival through centuries of suffering. Indians, preoccupied with holiness and spiritual snobbery, dampen playfulness, so original Indian jokes are rare. Each culture contributes uniquely; the highest humor is laughing at oneself.
Cultures that stay ordinary and can laugh at themselves (like Jews) create lots of jokes; when a culture stays very ‘holy’ and serious (like Indians), jokes are fewer.
