Mr. Monk Goes to the Dentist - S4-E15
Continuity mistake: When the Captain and Randy are talking in the garage, in the shots over Randy's shoulder, the pad on his guitar strap is over his shoulder. In the shots from behind the captain, the pad is behind his back and can't be seen. (00:24:40)
Mr. Monk Goes to the Dentist - S4-E15

Continuity mistake: When Randy is at Monk's place talking about hiring him, Monk says "Like who?" to which Randy replies "Like Me". While Randy says this he is holding a glass with one hand, the other being in his pocket. In the next shot, when Natalie says "Is it about the dentist?", Randy is holding it with two hands. Then, in the next shot, he is holding it with one hand again.

Mr. Monk Gets Jury Duty - S4-E16
Continuity mistake: When the man with the letter from the Attorney General is telling Stottlemeyer not to 'screw it up', he is moving the letter in his hand. However, every time we see Stottlemeyer front on, there is a corner of the letter in the shot, and the letter remains stationary even while the other agent is moving it.
Mr. Monk Gets Jury Duty - S4-E16
Factual error: Since Monk has OCD it would be highly unlikely for him to be on a jury. Plus, Monk works for the police department and since he technically works in the criminal justice system, that would have made him exempt from jury duty.
Suggested correction: First, he would have to ask for exemption in writing prior to serving, with proof, regarding hardship for his OCD. While it's possible his doctor might say serving jury duty would result in physical harm due to his mental illness, it's unlikely to be given by Dr. Kroger. And Monk is not an active peace officer, so that wouldn't earn him an exception.
Mr. Monk Gets Jury Duty - S4-E16
Factual error: When Natalie hears the jury's muffled screams inside the locked room she uses the fire extinguisher to tear off the door knob. But a locked door without a knob is actually only harder to open, because like that you cannot turn the mechanism even if it was unlocked.
