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".
This is the only cartoon where Elmer doesn't hunt Bugs in his usual hunting clothes.
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)).
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.
