In this episode of Science Vs., the hosts dive into the intriguing search for the world's funniest joke. They chat with comedians and researchers to uncover whether such a joke really exists and what elements contribute to humor. Although a large online experiment pointed to a joke about hunters as a contender, the hosts ultimately find that humor is deeply subjective, influenced by cultural context, surprise, and the feeling of benign violation. This makes the idea of a universally funny joke quite elusive. The episode sheds light on the complexities of humor, the scientific efforts to decode it, and the challenges of measuring something as personal as laughter.
