The Saga of Muley Jones - S5-E26
Revealing mistake: The Cartwrights' second cousin shows up and sings a lot. His singing breaks glass all over town. 1/4 of the way through the episode, while at the ranch, Ben is about to serve tea or coffee while Huley is singing upstairs. As Ben goes to pour it into a cup, the pottery kettle shatters but no tea or coffee or water comes out of the pot, showing it was empty.
Ben Cartwright: You and your education.
Adam Cartwright: Education is progress! Now what have you got against it?
Ben Cartwright: I don't have anything against education - as long as it doesn't interfere with your thinking.
Mrs. Wharton and the Lesser Breeds - S10-E17
Trivia: A portion of the background music used during an outdoor scene in the town of Vallejo was later used as the theme song for "Little House On The Prairie."
Question: How could one of the three have been in prison during the murder at the barbershop? Did he have a twin?
