Continuity mistake: In the very first scene, after the lead flunkie finishes his song, he turns around to speak to Margaret Dumont. When he turns back, look closely at his waistcoat - it's completely different.
Continuity mistake: While fishing on a dock, Stan crumples up part of a newspaper and throws it toward the water. When the newspaper blows back and hits Ollie's face, the pages are flat and uncrumpled.
Continuity mistake: Edgar Kennedy plays a cop who persuades Laurel & Hardy to break into the police chief's home so he can arrest them and "get in good with the Chief." Jimmy Finlayson plays the Chief's servant. When he hears noises, he stumbles at the top of the stairs and falls down the staircase. When he lands (it is obviously a stunt double), he is sprawled parallel to the stairs with his legs pointing to the right. In the close-up, he has reversed position and his legs are pointing to the left.
Continuity mistake: Oliver Jr. is soaked when he falls into the bathtub, but when he is boxing with Stan Jr. he now appears to be completely dry.
Continuity mistake: When she's confronting Bill, the maniacal look on Min's face disappears and reappears between full shots and close-ups.
Continuity mistake: When Oliver is laughing after Stan tossed the woman's bucket in the street, the top of Oliver's coat and his bowler hat are covered in snow. In the next shot, the snow has disappeared.
Continuity mistake: When Stan climbs out of the window to send himself a telegram, the window blinds are fully up inside the house, but when we cut to him going outside, the blinds are now a third of the way down.
Continuity mistake: Oliver Hardy is teetering at the top of a ladder which is in the back of Stan Laurel's car. Stan is driving west on Wilshire Boulevard when Oliver, and the ladder, fall into the street. Oliver gets back into the car but now is it inexplicably atop the streetcar tracks and facing the opposite direction.
