Ronda Jeter plays Opie's crush, Karen, in this episode. She appeared eight times in the series as basically the same character, but not always with the same name. Sometimes she had dialogue and sometimes she just appeared as a classmate visible in the shot. Her last appearance was in the color era, when she helped Opie learn how to dance in "Look Pa, I'm Dancing."
In "Andy and The New Mayor," Barney tells Jess Morgan he has a date at the duck pond. Andy then walks into the courthouse and tells Barney that Mayor Stoner thinks the duck pond on Willow Lane is getting to be a real "Lover's Lane" and he wants Barney to put up some "NO PARKING" signs. In this episode, Barney wants to take Thelma Lou to the duck pond. Barney either never put up those "NO PARKING" signs or plans to ignore them.
