Continuity: Sandler's tie changes from yellow (on the flight) to red in Hawaii. He doesn't have any luggage.

Continuity: After his arrival at Hawaii Barry calls his sister from a phone booth to ask her for Lena's hotel and phone number. From the side we see two men standing next to him, but between shots these two men get replaced by two women.

Visible crew/equipment: When Barry talks to the phone sex lady for the first time and she asks him if he is watching a porn movie there's a reflection of a crew member in the glass-framed picture behind him.

Continuity: When Barry tries out the harmonium that he has just put on his desk there's a chair standing behind him. When Lance opens the gate the chair is gone.

Continuity: When Barry cuts up his credit card you can spot some number sequences (000 and 21 344) which don't match the number he had given to the phone sex operator (5102 1717 8118 6554).

Revealing: When Barry is arguing on the phone with the Healthy Choices employee, the map on the wall behind him is creased in the Texas/Arkansas area before he punches it there. This could perhaps be the result of a previous take or some sort of indication of where the soft spot in the wall is so that Adam Sandler doesn't really break his hand.

Continuity: In the scene where Barry meets Lena for the first time there are a few shots through the gate where we see some cables and other junk on the wall across the driveway. When Lance opens the gate a little later everything is gone.

Continuity: After the truck hits Barry's car, he looks at Lena and blood is starting to flow down the right side of her face near her right eye. When he returns to the car, this blood is gone, but blood just starting to flow from above her right eye.

Revealing: When Barry is in Hawaii at the phone booth - notice they tried to cover up the Verizon logo, presumably to avoid free advertising, but it's still partially visible.

Continuity: After their first meeting Barry is watching Lena while she is walking away. He is holding a coffee mug in his hand with the handle away from the hand. When the camera angle changes as he goes back in he is holding the mug by the handle.

Continuity: The clock in Barry's office behaves very erratically. All the time he is mending the piano and cancelling his credit card it says the same time - half past 7. A couple of minutes later, when he is discussing Lena with his sister it reads about 10 past 8.

Continuity: When Barry punches the map, it falls down only slightly. The camera angle changes to him lying on the harmonium and the map on the wall behind him is much lower and at a different angle.

Continuity: When Sandler is demonstrating the new line of 'unbreakable' glass toilet plungers he smacks one on the table, it of course shatters and pretty much all of the white stuff inside comes flying. Yet later we see Sandler carrying the broken plunger handle with a lot of the contents still inside.

Visible crew/equipment: Near the end, Barry runs into the warehouse and gets the mini-piano. Just before he runs into his office, you can see the reflection of the camera crew in the office window.

Continuity: The scene where Barry and Lena meet at the hotel is shot very artistically. We only see their silhouettes when they fall into each other's arms, and immediately after that the silhouettes of an endless row of people rushing by them in both directions. However, in the shots before we saw each of them running towards the other, and there was absolutely nobody around except them. In addition, some of these other people walk by more than once, like a tall slender lady with flying hair.

Other: Barry tells the phone sex lady that she sounds very personable. The German subtitles translate personable with "vorstellbar" (imaginable).
