The episode contains what I believe is the only scene of the entire series that was filmed outdoors -- Rob riding on his horse in the Old West town. (There was one other brief outdoor scene in an earlier episode, but it was stock footage of a car driving along a highway and no characters were visible).
Sally: "Here's your favorite -- fried chicken."
Rob: "Oh boy, and hominy grits!"
Sally: "Oh, I don't know, about forty or fifty..."
Rob: "Hi, Buck. Howdy, Frank. Howdy, Jesse. Howdy, James. Howdy, Doody."
