Mr. Monk and the Billionaire Mugger - S1-E7
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.]
