As Savannah skateboards down the sidewalk toward Jake and Murray (the dog), she loses control and flips over a bush out of sight. Her skateboard remains behind on the middle of the sidewalk about midway on a driveway where the two intersect. The next shot is a point of view from Jake looking up the sidewalk, but no skateboard can be seen anywhere near the driveway and sidewalk intersection. The following scene shows Savannah returning to the sidewalk, but now the skateboard is on the sidewalk near the right edge of the driveway rather than at the original midway point.
On the second day that Jake wakes up while thinking Julianne is licking him (when it is actually Murray), his mother yells for him to wake up for school. In this scene she is wearing a pink shirt, the same shirt she wore the say before. A few seconds later when Jake comes down with his new outfit to impress Julianne, his mother is now wearing a light blue shirt.
Near the end of the first story, Savannah, who was standing behind Jake, disappears for one shot after the dog has trashed the science project and Julianne and her friends run out of the classroom.
In the twin/swap story, when Savannah first assumes Emma's persona & returns home, her jacket is buttoned crooked. As she enters the room for her dress fitting her jacket buttons are no longer misaligned.
