Continuity mistake: When Porky and Charlie go to the desert for their picnic at the end of the short, Porky sets up the picnic and plays "Fetch the Stick" with Charlie. Charlie then leaves Porky and when Porky rushes to his car after Charlie drives off, there is a trail of sand behind him. But after a quick cut to the car driving off, we return to Porky and the trail of sand has now gone.
Continuity mistake: When the mouse (hidden in a vase) tiptoes on the table at the start of the short, the bread on the plate is initially pointing up, but in the next shot it is pointing down.
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. But when we see Dale just a few seconds later, he is now sitting next to the tree and grass has suddenly appeared.
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.

Continuity mistake: During the poker game, the Colonel says "I've got five aces" and he lies down his cards in front of him. You can see that next to the Colonel there is half a coin and a pack of playing cards.

Continuity mistake: Mrs Waggett brings in a tray with cups of tea on it while her husband is on the phone, reporting the sinking of a ship that contained hundreds of bottles of whisky. Mrs Waggett puts the tray on the left side of the screen, then, taking two cups with her, moves to the right of screen and that's where she stays when her husband finishes talking on the phone and, amazingly, the tray that was on the left side is now in her hands, without her moving to the left side to collect it.
Continuity mistake: Bill Kirby enters the bar. He asks Bob the waiter about his wife. There's a cut during this brief exchange, and the girl sitting at the table in the background changes position suddenly (she was browsing a magazine, now she is holding it still and fully open). (00:02:35)
