Mr. Monk and the Other Woman - S1-E8
Plot hole: Monk says that the two files, both with tab at the middle, were kept together, which led him to discover that the person related to this file is 'the guy'. In an earlier scene, when Monk is searching the file cabinets, he picks up one of these two files and tells Sharona that this file is of 'the guy'. How can he say which one of the two files with middle tabs, which are put together, is related to 'the guy'? Impossible. (00:39:00 - 00:40:00)
