To make someone laugh, several effective approaches include smiling and laughing yourself to encourage a light-hearted mood, telling funny jokes or stories, showing something humorous like a funny picture, and doing something silly or playful. Playing dumb or exaggerating, using self-deprecating humor, and giving unexpected answers to yes/no questions can also create laughter. Additionally, using storytelling with humorous elements rather than just jokes, delaying the punchline for timing, and using callbacks to previous funny moments can enhance humor. Knowing your audience and reading the room helps ensure the humor is well received without offending anyone. Combining these techniques often works best to make someone laugh easily and naturally.
