Continuity mistake: When Gibbs catches McGee playing games on the MTAC system, McGee's microphone is down by his mouth. Camera cuts and it's up out of the way, instantly. (00:18:30)
Continuity mistake: When Ducky is doing the autopsy on the dog, he talks to the dog and leans against the slab on his elbows (the elbows are not seen however the motion is easy to distinguish). Camera cuts and his arms are wide and he's resting on his hands. (00:07:50)
Continuity mistake: When Gibbs is walking away from the FBI agent at the start, he is approaching a tree. As the camera changes he is way past the tree. (00:04:50)
