Continuity: After she talks on the phone to Jeffrey Moss, Ella stands up from the switchboard and walks around the room singing. When she returns the switchboard has changed place.
Continuity: When Jeffrey cleans a spot on the mirror, his left hand is leaning on the wall next the mirror. In the following shot his left arm is by his side.
Factual errors: As Jeffrey Moss changes the paper as he works on the outline for "The Midas Touch," the carbon paper between the blank sheets is shiny-side up. This would give him a mirror image on the back side of the first sheet instead of an original and a copy, which as an experienced typist, he would surely know.
Revealing mistakes: While Jeff is singing "I Met a Girl," various people in the background can be see mouthing the words along with him.
Errors made by characters (possibly deliberate errors by the filmmakers): Ella tells Jeff that she used to procrastinate by sharpening her Ticonderoga pencil down to the T (or rather the "tuh"). However, Dixon Ticonderoga say that their pencils have always read from point to eraser, so the T would be the *first* letter to disappear.
