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.

Plot hole: During the scene where the police are investigating the crime scene, Monk walks around without any protective footwear. Everyone in the room is wearing them, presumably to avoid contaminating any evidence. Monk regardless of his problems, would not likely be allowed to enter the scene without them. It could even be argued Monk would prefer to wear something like this. Additionally, it's not as if no one noticed. The husband even asks about whether he wiped his feet before coming in and Monk shows his shoes to him. The captain is even watching and comments about his shoes being extremely clean.

Continuity: The shape of the first ring Randy draws on the TV screen changes from an oval to a circle and then back to an oval between takes.
