Continuity: During Monk's therapy session, Dr. Kruger places his black folder on the arm of his chair. Every time the camera angle changes, the position of his right arm shifts from resting in his lap to lying on top of the folder.

Continuity: When Natalie props the get-well card up on Monk's bureau, it's partially open. The moment the shot cuts to a different angle, it's completely closed.

Continuity: Monk and Natalie question the landlady, Sylvia, about the missing guest. Every time the camera angle changes, Sylvia's arms change from being crossed in front of her to hanging loosely at her sides.

Other: In the flashback where Monk is explaining how the money was stolen, the principal finds the 5 dollar bill he wrote "good luck" on and holds it up for everyone to see. The bill he holds is a modern day 5 dollar bill which were introduced in the past few years, with the enlarged Lincoln. The flashback takes place in the 70s.

Continuity: In the flashback scene of the kids in the school hallway, the autographed photo of Patty Duke disappears and reappears twice on the inside of Little Monk's locker door as the camera angles change.

Continuity: When the kids are standing in front of the lockers, one of them is holding Monk's clarinet. The position of the instrument in his hand keeps changing between shots, from bell-up to bell-down, then bell-up again.

Continuity: When Alice is in Stottlemeyer's office and Stottlemeyer can't find Terry's present, Alice says, "But what about..." indicates the bottle of port, and then drops her arms to her sides. In the next shot (when we see Alice from the back), we can tell by the position of her elbows that her hands are not at her sides, but in front of her.

Continuity: When Alice confesses to the murder in her kitchen, a large green plastic bowl that's been sitting on the counter disappears between shots.

Revealing: The fan letter Monk wrote to shirt Inspector 8, shown in close-up where it hangs on her work station wall, consists of the same paragraph printed out twice.

Continuity: When the fashion designer draws a sketch on the newly painted wall, the drawing changes between shots, from four lines to about seven.

Continuity: When Cora goes upstairs, her cat is curled up asleep in a chair. In the next, close-up shot, the cat is awake and sitting at the edge of the chair cushion, looking up at Monk with its front feet hanging over the side. When the shot cuts to wide angle again, kitty is instantly back in his original position, snoozing far from the edge and curled up against the pillows.

Factual error: Debbie's pet bird is called a parakeet, but it's a much larger exotic bird. It's unlike Monk, whose other OCD eccentricities and obscure knowledge are in full force despite his amnesia, not to know the difference. Monk may not know every rare species by name, but parakeets (aka budgerigars) are household pets common enough that anyone would know Debbie's bird isn't one. Monk definitely would have known.

Continuity: In the hospital scene, the items on Gerald's tray change positions several times between takes.

Continuity: When Stottlemeyer goes to open the window in his house, the position of his body (especially his right arm) changes between shots.

Revealing: In their efforts to hide Gerald's pet mouse from the hospital staff, Randy and Natalie toss the rodent back and forth and alternate hiding him in their pockets. But every time he's tossed, Devo the Mouse gains weight. In fact, Devo's (stuffed?) stunt-mouse double is at least twice Devo's actual size.

Continuity: When the captain receives the victim's phone record (outside at the neighbor's house) he calls a number on the bill. But the phone starts to ring (on the other end) before he presses the last digit.

Continuity: When Monk is describing the laser pointer incident to Dr. Kroger, the doctor closes his black folder and puts it on the arm of his chair. In the very next shot, it's back in his lap, and he again closes it and places it on the chair arm.

Plot hole: The murderer mails a garage door opener with the button taped down to his victim and kills her by remote. But A) With the switch continuously in the "on" position, the battery would die long before the package arrived, and B) Door openers use special frequency tones that are set much like a safe combination. The likelihood of one control opening 3 different doors in the same area, as it does here, is virtually nil.

Continuity: When the Astronaut is talking to the kids in the classroom, the position of his arms changes from by his sides to folded between shots.

Continuity: When Monk has been chloroformed in his home and is gradually sliding down the doorframe, the dentist's assistant's hands go from being clasped under her chin in one shot to by her sides in another.
