Stan throws a stone which hits Fin on the head, but Fin is then seen holding his nose.

Ollie orders two more beers which, when they arrive, are mostly froth, but in the next scene they're mostly beer.

When Ollie first looks at the photo of himself, Stan, and their twins, he's holding it with both hands, but, in the next shot, he's holding it with only his right hand.

When Ollie is dragged out of the fallen telephone kiosk first, he's on his back then on his front.

When Stan and Ollie enter Denker's with their wives, a shot behind Alice and Liliy shows cocktail glasses on the table. The next shot, in front of them, has the beer glasses from the first encounter with Bert and Alf.

The bartender (Joe) forces Bert and Alf to give him the captain's ring as a deposit to cover the damage they caused to the phone booth until they can return with the cash to pay for it. However, when Stan and Ollie arrive with their wives, Joe makes no mention of his previous encounter with their identical twins.

In some shots on the dock when Stan and Ollie are swaying in the cement, the wires used to keep them upright are visible.
