A line from Bugs' phone conversation, "Is that you, Myrt? How's every little thing?", is lifted from a running gag on the popular radio show "Fibber McGee and Molly".
The Elmer character is in a transitional state from his earliest appearances in Robert Clampett's shorts and the appearance which he adopted around 1943.
This is the first cartoon where Bugs cross-dresses; at one scene Bugs disguises as a woman in lingerie, when entering one of the rooms in Elmer's house, and Bugs (in drag) screams when Elmer opens, causing Elmer to close the door, only to realize that he has been tricked (This gag would later be re-used in Hare Trigger (1945)).
Bugs fakes catching pneumonia when getting thrown out of the house in one scene, which he remarks that scene will win him the Academy Award. Despite this comment made by Bugs, this cartoon was neither nominated for nor did it win an Academy Award. Bugs would repeat this gag again in Hare Force (1944), when Sylvester the Dog throws him out from the house and into the cold.
The song "Angel in Disguise" is from the 1940 Warner Brothers film It All Came True (1940) which, like The Man Who Came to Dinner (1941), starred Ann Sheridan.
