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.
