Goofs

Though Stan and Ollie never do manage to fix the flat tire, it's in good condition by the end of the film.

A neighbour throws a jack through the bottom part of the car windscreen leaving the in between piece of rubber hanging down but it subsequently disappears.

When Ollie emerges from the kitchen with the tray of sandwiches, he drops one (you can see it clipped to his fingers). But after showing the closeup of the sandwiches the drop is repeated.

As the family set off for a picnic a tyre on the car gets a puncture. but in the course of trying to change tyres the punctured one is put back on and not changed again before the family drive off.

The last scene has the car sinking in the water. You can see a reflection of a man and a camera in the upper part of the windshield, as the car goes down.
