Personality
Gibbs displays a continuous urgency about the investigation he pursues, specifically when being given technical information about, complex subject matter. The typical response to such information is "Give it to me in English", thus forcing the expert to get to the point, as well as making it easy for the audience to understand. He also displays elements of sarcasm particularly in relation to someone in his company stating something obvious, the typical sarcastic answer "Ya think?" is his preferred retort.
He is a dedicated coffee drinker, a fact played out with his team setting up someone to innocently drink or spill his coffee, incurring Gibbs' ire. In the episode "Forced Entry", when McGee drinks Gibbs' coffee unawares, an on-base security officer explains that rule #23 is "Never mess with a Marine's coffee if you want to live." At episode's end, Gibbs endows McGee with his coffee as a thank you. In the episode "Hiatus (Part 1)", Ziva claims that if Gibbs had been killed in the explosion on the ship, the color of his guts would "be more coffee brown than red."
His hobby is woodworking. Gibbs is shown to always have a wooden-hulled sailboat under construction in his basement, which he builds entirely by hand using no power tools. In the episode "Tribes", he tells FBI Agent Langer: "Finished it twice. This is number three." He later tells NCIS Director Jenny Shepard that he is working on his fourth boat, and that he named one of the previous boats after his (then current) wife when he finished it, then burned it after their divorce. When asked why he didn't simply sell it, Gibbs replies that he "couldn't stand to see someone else sailing Diane." Dr. Mallard tells Colonel Mann that another of Gibbs' boats was named after his daughter, Kelly. It is not revealed what Gibbs did with the other completed boats, nor how he could remove their twenty five foot hulls intact from his basement. When asked by McGee, Gibbs cryptically replied, "Just break the bottle." In the episode "Honor Code", when Gibbs is talking with a Lt. Commander's son, he does mention a possible method which would involve taking down part of his wall and hauling it out through the now wide enough space, thus breaking the bottle.
One of Gibbs' "trademarks" is that he will often slap the members of his team on the back of the head when displeased with their performance, though he does this mainly to Anthony "Tony" DiNozzo as opposed to other members. When Gibbs "retired", and Tony gained his position as leader for a short while, Tony often slapped the team members in a similar fashion; in the episode "Hiatus (Part 2)", Mike Franks is shown slapping Gibbs in the same manner in a flashback. As revealed by Ducky in the episode "Mind Games", about ten years earlier he was just like Tony. From an exchange with Ducky, one of Gibbs' divorces (ten years earlier) was partly caused by his working on a serial killer case and making it impossible for his wife to stay, but according to Gibbs she was the one who left him. When asked why he slaps his team only on the back of the head Gibbs responded that "a slap to the face would be humiliating, back of the head is a wake up call." At one point he also threatens to slap Abby, though not on the head.
When somebody mentions the loss of children and wives, Gibbs rarely comments although he may react slightly. When Todd was killed, Ducky, who at that point did not know of Shannon and Kelly's story, mentioned that Ari was targeting women and neither of them (Ducky or Gibbs) has ever lost a loved one, to which Gibbs paused and didn't say anything.
In the episode "Faking It", it is revealed that Gibbs speaks Russian and at least a little Japanese and Chinese (Call of Silence and My Other Left Foot, respectively). He also signs American Sign Language, which appears in many episodes in conversations with Forensic Scientist Abby Sciuto.
Gibbs is often noted to be extremely protective of and comfortable around Abby, often massaging her shoulders, buying her favorite energy drink (the fictional Caf-Pow), and kissing her cheek.
