Continuity: When Natalie quizzes Monk on the finer points of ice hockey, a blue teapot sitting on the kitchen island beside her moves itself back and forth several inches between takes.

Continuity: When the murderer strangles his victim, her music box is dropped on the floor several feet away. Though no one has touched it, the music box is somehow lying only a few inches from her body when the police arrive to investigate.

Continuity: Monk leaves his front door standing open in anticipation of his new friend's arrival. No one goes near the front hall, but when Hal gets there, he lets himself in by opening a door that has somehow closed itself.

Continuity: At the end, Monk points a gun at Hal. But between takes, the weapon shifts instantly from his right hand to his left and back again.

Continuity: At the end, the crime is reconstructed and in flashback, we see and hear the murderer makes his fake 911 call. But his words do not match the 911 tape played earlier in the episode.

Continuity: Monk finds the magazine from which the butler cut out words for his blackmail note, and matches a scrap with the word "Police" on it to the article it was cut from - only the left and bottom edges of the scrap don't conform at all to the hole cut in the page. They haven't been trimmed more. In fact, the whole piece is much too large to fit into the space.

Continuity: Natalie carries a large box full of house plants into Monk's kitchen and starts placing them one by one on the counter while he answers the phone. Each time the shot changes, a large red flower switches itself from the left side of one plant to the right side and back again, and sometimes disappears altogether.

Continuity: As the murderer is arrested at the end, the collar of his jacket changes from turned up in back to turned down, etc., several times between takes.

Visible crew/equipment: Inside the CSI van, when the investigators all turn to look at Randy, an equipment shadow sweeps across the wall at the upper right of the screen.

Continuity: When Monk, the Captain and Disher talk to Dr. Scott during his cardio test, the doctor's hospital gown is falling off his left shoulder in about half the shots, but is pulled up to his neck in the rest. This alternates several times throughout the scene, though he never touches or adjusts the gown.

Continuity: In the hospital corridor, when Stottlemeyer orders Monk to go home, the items on the nurse's station counter shift positions completely every time the camera angle changes.

Continuity: Ringel closes the blinds, then turns and walks away from the window. After a brief shot of Monk and Marcy, Ringel turns and walks away from the same window again.

Deliberate "mistake": It's out of character for Monk, a chronic stickler for details, not to correct an error, especially one relating to his own life. Marcy's diorama for "Mr. Monk & the Three Pies" includes Natalie, who wasn't around yet when "Three Pies" occurred. The doll should be of Sharona, not Natalie, but since that would ruin the ensuing joke, Monk was allowed to overlook the mistake.

Continuity: In the lumber yard, Randy shows a rare streak of genius by knocking out the bad guy with a 2x4 shoved through a stack of boards. When the 2x4 strikes Ringel, it stops its slide protruding about six inches from the stack. When the camera angle changes for the very next shot, the 2x4 is suddenly sticking out more than a foot.

Continuity: Near the end, when Ringel pulls a gun on Monk and Marcy, he reaches over and closes the venetian blinds. There's no gap in the shuttered blinds when he walks away from the window. Then there is. Then there isn't again.

Factual error: While the police are investigating the murder at the start of the episode, there is no sheet over the body or tent to cover the body. Being they are on a beach it would make sense to cover the body from any small debris or sand blowing onto the body. The sun is also shining brightly. I don't think the heat would help the coroner with the autopsy especially since it's murder.

Plot hole: There is a dead body on the beach, police all around and none of the public are even curious at the crime scene. There is quite a number of people at the beach and only a few people even take a glance at the body which is additionally uncovered. If there was no one around then it could be understandable, but the fact that no member of the public is even trying to look or even upset by this is just impossible to believe.

Continuity: A little white pillow on Natalie's couch falls over when Monk gets up, then rights itself again when he's in the kitchen.

Continuity: While Monk and co. question Vicky's roommate, two throw pillows behind her on the couch shift their orientations several times from shot to shot. The larger one also moves from the couch corner to a spot behind the woman's left arm and then back again.

Continuity: In the mausoleum, the bald man asks Monk and Natalie what happened to the cremation urn name cards, and bends to pick one of them up from the floor. There are no cards on the table when he does this, but in the next shot, four cards have appeared on the table out of nowhere. A short time later, they've all disappeared again.
