The title of this episode is from a line in Shakespeare's "Taming of the Shrew"; And now I see her lances are but straw.
After using a 1960 Chevrolet Corvette only in S1, E1, the producers went to a 1961 model starting with E2, and for the rest of the first season. The '60 was a light, bright blue that was hard to photograph well in black and white. The '61s used were either a fawn beige or a very light green metallic, ideal for lighting properly in black and white.
