S6·E24 Lisa the Psychologist

Lisa & Oliver decide to take a college course together in Pixley. Oliver chooses a farming course meeting on Mondays, Wednesdays & Fridays and Lisa decides on a Psychology course, simply because it meets on Tuesdays & Thursdays. After a few lessons, the zany members of Hooterville become enthralled with ""Doctor Lisa"", who helps solve Eb's, Mr. Kimball's and Arnold's problems with logical reasoning. Mr. Haney tries to sell Oliver a pyschiatrist's couch once used by Dr.Sigmund Frood. An exasperated Oliver has to make an appointment with ""the doctor"" when he intrudes on Mr. Drucker's psychiatric visit. Lisa gives up her practice to be Oliver's wife again.
