Sheng Wang on the art of being present and writing a good joke

Sheng Wang is a comedian and writer from Houston who has spent 20 years quietly refining his craft at comedy clubs in San Francisco. His second Netflix special, Purple (directed by longtime friend Ali Wong), is a collection of jokes about the small, mundane parts of life that most people don't give a second thought. He talks to Tom Power about his comedic inspiration, the process of writing a good joke and his love of a botanical garden.
