Why Do People ‘Laugh’ at the Same Jokes?

Imagine you and your friend hear a joke, 'Why did the chicken cross the road? To get to the other side!' Both of you laugh. It’s like your brains are connected in a secret way, making you feel the same joy at the same time. That connection is called shared laughter. When people hear the same jokes, their brains light up in similar ways, just like two friends who know each other's inside jokes.
