Directed by Alec Berg
Written by Larry David
Larry takes Loretta to see a doctor who urges patients to "walk out on cancer" by getting rid of toxic spouses, hoping she may be counseled to dump him. Larry's attempt to do a favor for Leon backfires, when he inadvertently tips Leon's friend off to the fact that Leon's sleeping with his wife. Several misunderstandings around fellatio lead to Larry offending Richard Lewis's new girlfriend - and Loretta leaving Larry, and taking the rest of the Blacks (except for Leon) with her.
