Continuity: 7-1 "Mr. Monk Buys a House": In the hardware store, a bright blue sign in the background reads "Electrical" in reverse. When Jake hands Monk his card a few shots later, the camera angle hasn't changed, but the sign has turned around and now reads "Electrical" forwards.

Revealing: 7-1 "Mr Monk Buys a House": When the visiting nurse pushes the old man down the stairs, it is very obvious that the man falling down the stairs is not the old man in the wheelchair. His hair is not even close to the same color. Bottom line: horrible stunt double.

Continuity: This mistake occurs when Monk and Natalie are sitting on the stairs watching the two men wrecking the walls. Close up shots show Natalie sitting with her legs crossed while the long shot shows her legs bent at the knee side by side.

Visible crew/equipment: 7-1 "Mr. Monk Buys a House": When the coroner's van pulls up in front of Cassie Drake's house, its shiny black side panel captures a clear reflection of the entire film crew.

Continuity: When the victim's niece is crying and Monk is quizzing her about the house, the position of her hands changes instantly several times as the camera reverses angles. She holds her hands to her face as she cries, for instance, but in the very next shot, her hands are down at her sides. Next cut, they're up to her face again.

Visible crew/equipment: After Kloster catches Monk breaking into his house, the boom rigging's shadow can be seen moving on the wood-panelled wall in the background.

Continuity: When Monk is telling Captain Stottlemeyer about Trudy's death, he says that by the time he got there, she wasn't even able to speak, that she held his hand and died. However, in "Mr. Monk Meets Dale The Whale," we learn that Trudy's last words were "Bread and butter," and that she said them to Adrian right before she died.

Factual error: 7.5 "Mr Monk is Underwater": Lt. Albright shows Monk and Natalie the "USS Seattle", a "Class 4 Submarine". US sub classes have names, not numbers, so she would be Los Angeles, Seawolf or Virginia class.
