Continuity mistake: When Sharon asks Sydney's old flame about the mugging 20 years ago, the glasses in front of them are full when they are being filmed from behind Sydney's ex, then are half empty being shown from behind Sharon, and in the next shot they are full again. (00:32:00)
Continuity mistake: It's spring in San Francisco in this episode: warm with light rain and people outside in shirtsleeves. That is, until Monk goes to visit Kelly, when it suddenly becomes winter. Everyone's bundled in heavy coats and it's sleeting. After Monk leaves Kelly's house, it becomes spring again. [The Kelly Street sequence was originally meant to be used in "Mr. Monk and the Candidate, " where everyone is dressed appropriately for cold weather. For whatever reason, it instead got used in this episode.]
Continuity mistake: In the opening scene, Archie Modine pulls the revolver on Sidney Teal with his right hand and fires one shot. The camera angle changes as the remaining shots are fired and Modine now has the gun in his left hand and is standing in a completely different stance. During the recap of the crime at the end of the episode, Modine fires every shot with his right hand.
