Continuity mistake: When the inebriated cuckoo pops out of the cuckoo clock at the beginning of the cartoon, the edge of the door is coloured green but changes to red in the very next shot.
Trivia: At the beginning of the cartoon, we see a long line of books at the book shop. The last book we see is entitled "Life and Times" by Bugs Bunny.
Daffy Duck: Swing music. Jazz. Phooey! Ah, bublichas, how difference in my native willage. Soft music, wiolins, the happy peoples sitting on their balalaikas, playing their samovars. And then, there was Cucaracha. Ah, Cucaracha: so round, so firm, so fully packed, and so easy on the draw. They would sink to me a little gypsy love song, like this. Listen. CUCARA-CHA! Cucaracha, cucaracha - hoo hoo hoo hoo! Cucaracha, cucaracha - hoohoohoohoo.
