Betty Grable is referenced several times in this episode. She was an American actress, pin-up girl, dancer, and singer. Her films during the 1930s and 1940s grossed more than $100 million, and she set a record of 12 consecutive years in the top 10 of box office stars.

This is Dave Willock's only guest appearance in the series. He appears as a German captain who promotes 'Private Hans Wagner', actually Carter in a German uniform, to an acting corporal.
In this episode, Newkirk signed papers as 'Newkirkheim'; in another episode, he was 'Newkirkburg'.
The German captain makes Carter, as Private Hans Wagner, an acting corporal. In later scenes, there are no corporal's stripes on the uniform Carter is wearing.
