Character mistake: In Frank Sinatra's scene in the taxi cab, when the girl is singing "Come Up to My Place," he rolls the cab window down and when he rolls it back up, he catches the front of his hair (the quiff) and has to roll the window back down to release it.

Continuity mistake: When Chip and Dale fall out of the tree after Donald had drilled in a hole in it to get some nuts, Dale lands on the ground and you can see there is nothing on the bottom of the tree.

Continuity mistake: Before Elmer's two dogs shake hands on agreeing to catch Daffy, one of them draws a diagram which is a dotted line and a circle with a cross in it. After the two dogs run into a tree, they go back to their meeting point and this time the diagram is completely different to the one drawn before.
Visible crew/equipment: After the opening credits and intro at the start, in the first shot, just before the 'Britton and Sons Hats' glass door begins to open inward, the reflection of the camera and cameraman can be seen on the glass surface. (00:01:40)
Continuity mistake: When we see "Grandpa's Folly" being 'scratched' in his starting box, the box has no door in front of it, but when we see the boxes at the start of the race in the next shot, a door has suddenly appeared.
Continuity mistake: After the ill-received Al Jolson impersonation, Milton Berle gets paid only 5 bucks instead of 50. He asks the manager "What are you doing, putting 45 in your own pocket?" as several not so reassuring individuals begin to crowd him. Notice a balding guy with a white shirt and pattern tie; he puffs out smoke as he arrives, but at the cut he is still chewing on his cigar and immediately blows smoke again.
Continuity mistake: When the City Wolf hits the Country Wolf with his baseball bat, the bat he is holding has an oval shape on it. When the City Wolf says "Control yourself, cousin!" in the next shot, the oval shape has disappeared.
