Trivia: When we see Elmer pointing his gun at Bugs in order to make him do his second curtain scene, you can see behind Bugs a crate saying "5 Clampett Trained Seals" - a reference to the Warner Brothers director, Robert Clampett.
Continuity mistake: When the curtain raises before Bugs Bunny does his tap dancing act, you can see the background behind him only has a columned building but in the next shot a mansion suddenly appears.
Bugs Bunny: I'll do it, but I'll probably hate myself in the morning.
