Continuity mistake: When Fred is reading his letter about his position being accepted at the Stone Valley Inn, you can see Wilma is sitting in the chair next to him, but in the next shot the chair is empty and Wilma is nowhere to be seen, then she reappears in the chair.
Continuity mistake: When Fred and Barney discover that the football match on TV has been postponed, we see an interviewer sitting at the desk and you can see there is a nameplate saying "T.V." in front of him, but when the interviewer introduces Eppy Brianstone in the next shot, the nameplate has disappeared.
Continuity mistake: When Barney asks Fred if he could have 25 cents for a sandwich whilst practising their ventriloquism act for "The Ed Sullystone Show", you can see Barney has his left arm on his knee, but when we see a close-up of Fred in the next shot, Barney's left arm is missing.
Continuity mistake: When Barney shows Fred the ad in the paper about new novelty acts for "The Ed Sullystone Show", the ad says "Apply Bedrock Broadcasting Co" at the bottom. When we see Fred and Barney in the queue with the other applicants, the station is now called "Bedrock Television Company."
