Mr. Monk and the Three Julies - S6-E13
Character mistake: Julie has just passed her driver's test. At the end, she drives up with two teenage friends in the car and offers the stranded Captain Stottlemeyer a ride. Instead of simply accepting, by-the-book cop Stottlemeyer would be lecturing her. California law prohibits new teenage drivers from having other teens in the car. (00:40:15)
Mr. Monk and the Three Julies - S6-E13
Character mistake: When Monk's examining the second dead Julie, notice that Randy touches the body to point out a bruise. Surely real life cops would be wearing gloves so as not to contaminate part of the crime scene.
Answer: Notice also that in the opening credits scene when he is touching parking meters her also wipes his hand on his clothes each time he does it.
