Patton Oswalt explains why stealing jokes is “no laughing matter.”

Patton Oswalt fully admits that he has accidentally used another comedian’s joke before. It happens to comedians. But there is a fundamental difference between someone who uses a joke by accident and stealing a joke.

In August of 2017, Conan O’Brien was in the middle of a legal battle over (allegedly) stealing jokes and using them on his show. With the evidence stacked against O’Brien, other comedians began speaking up on the seriousness of joke theft. VICE News sat down with Oswalt to get his take on subject. Unfortunately, because Oswalt is a witness in the O’Brien case, he cannot talk about the case directly.
