Continuity mistake: When Monk is trying to join the two cops' conversation about football, in the shots from the side of the police car that they're standing near, the two cops are standing less than a foot apart. In the shots from the other side of the car, they're far apart enough for Monk, Natalie, and Captain Stottlemeyer to stand between them. (00:03:00 - 00:05:00)
Mr. Monk Goes to the Office - S4-E4
Continuity mistake: When Monk and Natalie are talking to Kemp in his office, the desk ornament and the cup of pencils that Monk keeps organizing change positions between shots. In the shots from Monk's side of the desk, the ornament is closer to the door. In the shots from Kemp's side, the pencil cup is closer. (00:09:40 - 00:11:20)

Continuity mistake: When Natalie and Al are struggling, the gun lands on the table and there's a basket of corks. Somehow when Al gets the gun, the basket is tipped over and the corks are on the table. But after Monk hits Al, the corks are all back in the basket, which is upright.
Continuity mistake: When Monk and Al are sitting to drink wine, Al grabs his bottle with one hand to pour the wine and the other hand is hanging down to his side. In the next shot, as he's pouring the wine, he's holding the glass with the other hand. In the next shot, his hand is by his side again.

Mr. Monk and Little Monk - S4-E8
Continuity mistake: When Monk is doing the summation for the present-day case with Sherry's ex-husband sitting in the chair, at first you can see that the painting is directly behind him. However, shortly thereafter during the summation, the painting has somehow shifted to the viewer's left and is no longer directly behind him. While it's plausible that someone could have moved the painting, it's just not believable since less than a minute has passed. Besides, would Lt. Disher (he was closest) really take it upon himself to move evidence?
Mr. Monk and the Secret Santa - S4-E9
Continuity mistake: In the beginning scene it shows someone injecting a liquid, with ease, into what appears to be a corked wine bottle. Then around the 13-min mark you see the Captain re-gift the bottle and when the person opens it, it's a pull cork with a hard top, something a needle would not easily go through. (00:00:10 - 00:13:23)
