Continuity mistake: When the man from the draft board says "Well now, I wouldn't say that!" to Daffy in the closet, Daffy has one hand on the handle. In the next shot, he can be seen holding the handle with both hands, and in the shot after that, he is holding it with one hand again.
Continuity mistake: When Daffy opens the door and sees the man from the draft board, the door is plain and grey. But when we seen a close-up of the man, the door is now blue with moulding, and when Daffy slams the door on him, it is now grey again.
Continuity mistake: When Daffy sees the man from the draft board, he puts various items in front of the door to prevent him from entering. But when he goes to the door with his packed suitcases, the items have all gone.
Continuity mistake: When Daffy is placing items on the door to prevent the man from the draft board from entering, there is a pull-down blind on the window, which wasn't there when he closed the window after seeing the man.
