Laughing makes us feel real good, whether you’re in on the joke or not. But does it serve a specific purpose? Why do we find some jokes hilarious and others to be total groaners? In this episode, Tai peels the science and sociology of laughter down to its evolutionary roots.

In this episode Tai talks to:

- Sophie Scott, professor of cognitive neuroscience at University College London and stand-up comedian

- Andrew Phung, actor, improv comedian and creator of the sitcom Run the Burbs
