Trivia: The "Instant Girl" jar that Daffy Duck picks up towards the end of the cartoon credits the "Pierce Packing Co." This is a reference to Tedd Pierce, the writer of this cartoon.
Continuity mistake: When Quackie is hit on the head by a club at the Club Car in the train, he stands outside the car and you can see the words "Club Car" on the door. In the next shot, the words have gone.
