The car Bud Abbott and Lou Costello are driving in the early black-and-white section of the movie is a 1951 Henry J, which was manufactured by the Kaiser-Frazer Motor Co. and named for founder Henry J. Kaiser. In addition to being bought from an authorized dealer, the car could also be ordered through the Sears-Roebuck mail-order catalog, although its name was changed from "Henry J" to "Allstate".
Bud Abbott and Lou Costello made an independent, two-picture deal in which they agreed that this was to be "Lou's film" and the next to be "Bud's". They retained individual ownership of the respective films.
Early in the movie, when Jack (Lou Costello) first meets the employment agency's receptionist (Dorothy Ford), he tells her: "I like girls like you, eyes of blue and five feet two". This is a reference to the refrain of the 1920's popular song, "Has Anybody Seen My Gal?" It's only after she rises from her chair that he realizes his misconception; he is dwarfed by Dorothy Ford's 6' 2'' (1.88 m) full height.
