'No hugging, no learning' policy

Larry David had a very unusual rule that he made all the cast follow.

In order to avoid any unwritten changes to character dynamics, the writer enforced a "no hugging, no learning" policy on the cast and crew.

He explained: "A lot of people don't understand that 'Seinfeld' is a dark show. If you examine the premises, terrible things happen to people. They lose jobs; somebody breaks up with a stroke victim; somebody's told they need a nose job. That's my sensibility.”
