A previous post said there was no laugh track at all, which was refuted by a critic here. There is a very faint laugh track on the MeTV rerun of this episode. However, it was so quiet that it barely registered on the show.
This is one episode where the date is seen as being in 1943, as Hogan has a poster promoting the show "Escapes of 1943".
This episode has no laugh track at all. NB: It does on Freevee as of March 31, 2023.
Ben Wright previously played a Nazi in the Rogers and Hammerstein musical The Sound of Music (1965).
