What was the title of House M.D.’s 2005 episode about three medical cases?

The 2005 House M.D. episode about three medical cases is titled “Three Stories.” It is the season-one episode in which Gregory House teaches a lecture using three patient narratives to explain diagnosis and medical reasoning.

“Three Stories” is structured unusually for a television medical drama. The stories move through different situations while House guides medical students through the diagnostic process. The episode also reveals important information about House’s own leg injury and chronic pain, giving personal history to details introduced earlier in the series.

The episode was written by David Shore and directed by Paris Barclay. It received major critical acclaim and won the Primetime Emmy Award for Outstanding Writing for a Drama Series. Its title refers to the three case narratives, not to three seasons, three doctors, or three hospital departments.
