Teenage neighbors find the body of a Marine, LCpl. Korby, who apparently committed suicide by carbon monoxide; Gibbs and company investigate; Ducky promptly says that the death was not by suicide, and he soon sees irregularities. Ducky elaborates on his hypothesis against suicide, and Abby adds details. Korby was a practical joker whose pranks often displeased others; some of his tricks had caused problems within his outfit, and his fellow Marines had taken action. Tony consistently believes that Korby's wife killed him; he eventually starts to arrest her, but Gibbs stops him. Gibbs, Tony, and McGee put the right pieces together, and they bust the person responsible. Finally, Tony experiences a dental problem. Written by

Abby calls Gibbs back to the monitor as she's found something in one of the scans; the scene then shifts to show the gaseous makeup of the sample (Turpentine, Nitrogen, Acetone, and Benzine). Benzine isn't C6H6, benzene is; benzine is also a petroleum fragment and rather hard to handle outside of a laboratory setting as its boiling point is somewhere between 42 and 62 degrees Centigrade (107.6-143.6 degrees Fahrenheit) and its flash point (the temperature at which it can be set on fire with assistance) is less than 0 degrees Centigrade (32 degrees Fahrenheit).
