Continuity mistake: When Bugs is conducting the orchestra at the end of the short, the stand in front of him is black but changes to brown in the next shot.
Continuity mistake: When Bugs takes Elmer's fishing rod away from him, he pulls on the rod and Elmer goes through the hole that Bugs burrowed through and out of Bugs' home. But when Bugs walks off after throwing Elmer away, the hole that he burrowed through is nowhere to be seen.
Continuity mistake: Before Elmer Fudd does his high diving act, you can see the pot behind him has a plant in it but in the next shot the plant has disappeared.
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.
