Mr. Monk and the Bully - S7-E14
Continuity mistake: When Monk and Natalie are arguing at Monk's apartment, Natalie is wearing a ponytail. However, when the scene cuts to them standing in Fendle's hotel room, Natalie's ponytail is gone, and does not reappear for the rest of the episode. It's the same day, however, since she's still wearing the same dark black coat in both scenes. The most likely explanation is that the scene in Monk's apartment was filmed concurrently with Natalie's scenes in "Mr. Monk Makes the Playoffs" - the black-collared shirt Natalie is wearing in the second half of the episode appears to be the same one she wears in the previous episode, where her hair is in a ponytail for most of her scenes.
