A Pest in the House

Audio problem: When Daffy is singing when cleaning the window in the businessman's room, his beak doesn't move when he sings "passes you by."

Audio problem: When Elmer pushes the bell on the reception desk at the end of the cartoon, Daffy turns up and says "Yes, sir?" but his beak doesn't move.

Other mistake: When Daffy is helping the guest to his room, he looks at his keys as to which one would open it. When he finds the right key, he somehow manages to open the door without unlocking it.
