Character mistake: At the start, Kort takes the gun from one guy and uses it. He then places it at the second man's body without wiping it for prints. When he swaps his gun though, he wipes it for prints. Why didn't he wipe the first gun he used? (00:00:50)
Visible crew/equipment: When they arrive at the funeral, a crew member is seen in Gibbs' car's paintwork. (00:35:30)
Visible crew/equipment: At the start of the sexual harassment class, when Tracy Taylor explains, "A coworker shows you a cartoon or photo of a sexual nature," we can see three orange T-marks taped to the floor near her. (00:02:55)
Honor Code - S3-E7
Other mistake: At the end of the episode Gibbs has a flashback where his daughter is helping with a boat. She is in an NCIS shirt, but Gibbs had no association with NCIS while she was alive.
Bikini Wax - S2-E18
Audio problem: When Abby tells McGee to shut up near the end, the audio is out of sync with her mouth. (00:34:40)
Continuity mistake: When Gibbs has the Mafia boss against the car, his arm is across the Mafia guy's chest. Camera cuts and now it is right next to his neck. (00:34:50)
Continuity mistake: Just after Fornell is arrested, the agents are showing NCIS their surveillance of the mafia. When doing so, the headset on the one agent changes position instantly. (00:22:00)
Continuity mistake: The amount of sandwich Tony has eaten when Abby is being hacked is constantly changing instantly. (00:13:00)
Continuity mistake: The banana peel on DiNozzo's index finger, healing his owie, moves to his thumb in one shot. (00:12:00)
Character mistake: In the scene, where Jeanne tells Tony that he never said he loves her, besides after sexual activities. This is not true. In episode 15 "Friends and lovers" Tony ends a phone call saying "I love you."
Visible crew/equipment: When Abby is going through the garbage to disprove Tim's sister you can see a crew member's foot in the screen- it's a brown boot.
Factual error: When Tim is tracing the British agent's mobile phone it shows that the number traced is a British land line number (01632) not a mobile number (starting 07...). The number is also seven digits long, not six as is the format in the UK.
Factual error: In the yacht rescue scene the "American" crewed helicopter is actually an Australian crew. The rank on his shoulder shows an Australian Lieutenant Commander. (00:34:30)
Continuity mistake: When Tony enters the NCIS interrogation room with Fornell, he sits down and places his bag of potato chips on the table. In the next shot, the bag has disappeared, he removes it from his jacket pocket, and places it on the table again. (00:25:15)
Continuity mistake: When Gibbs stops Sgt. Roberts from killing his neighbor, he holds out his ID badge. His hand jumps from the top of the wallet to the bottom, then back to the top. (00:31:20)
Character mistake: When Gibbs tells William Danforth that the body in autopsy isn't his son, he says, "Not according to AFIS." AFIS is the fingerprint database; since the body was identified using DNA, Gibbs meant to say "CODIS." (00:13:50)
