Mr. Monk Gets Cabin Fever - S3-E12
Factual error: Randy calls the cabin and gets a "not in service" message. But he should have heard an unanswered ring instead. The FBI agent tore the cord from the wall, which in the US does not generate a "not in service" recording. That only occurs when the phone company cuts off your service due to non-payment or cancellation. (00:30:00)
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.
