Character mistake: When Dean Martin desribes his writer's block to Judy Holiday, she says that she keeps sharpening his Ticonderoga pencil until there's nothing left but the "Ti," but in fact what would be left on a little nib is the "ga."
Suggested correction: She said she would sharpen her pencil... to the "t."
You should watch the whole scene. She said she would sharpen it to the Ticondero, and then to the Ticond, and she keeps going until the "Ti" and "T" (where she pronounces the sound rather than the letter).
