Petticoat Junction - Season 2 Episode 8

The girls are trying to learn some Japanese to make Betty Jo's Japanese pen pal, Nobuko Takamura, feel at home for her visit. Nobuko has come to the US to attend college to improve her English so that she can teach it back in Japan. She would also like to learn American customs. Nobuko tells Joe that in Japan, the women do the yard work. Joe gets Nobuko to do his chores until Kate puts a stop to it. On a picnic, Nobuko can't help but serve Billie Jo and Bobbie Jo's boyfriends. Kate tells Nobuko that the men should be the ones helping the women. Nobuko catches on to that custom quite quickly.
