The wall lamp Porky turns off vanishes in the next shot and is not seen again.
The bedroom becomes considerably smaller between the cat and dog fight scene and the pesky moon scene.
When the clock goes off at 6 am, it is in front of the mirror on top of the bureau. When Porky shoots it at 8:15, it has moved to a table to the left of the bureau that was not even there at 6.
After the alarm clock goes off at the beginning, Porky and Daffy continue sleeping while the clock runs until 10:00 AM. When the view shifts back to the bedroom, the clock hands look like it is 11:50 (i.e., the big hand is on the 10 and the small hand is on the 12) instead of 10:00.
When Porky throws the shoe out the window at the meowing cat, as he walks to the window, the alarm clock shows the time as approximately 10:10. It was 8:05 when he got out of bed to throw the shoe.
Why do Porky and Daffy have to get up at 6:00 AM when their clock in time is 8:00 AM, and it takes less than 15 minutes to drive to or from the Fly-By-Nite Aircraft Co.? On Sunday they got up at 6:00, threw on their clothes, got in the car, drove for 15 minutes to the company, realized it was Sunday, drove for 15 minutes back home, and got back in bed - all in 2 hours and 15 minutes. There is no indication what they did for the hour and forty-five minutes unaccounted for, since they would have arrived at the office at 6:15, not 8:00.
