NCIS 

Best T.V. show out there. Can be a little corny at times but it is not your usual dry, boring, no personality investigative show. I would advise everyone to invest some time in watching this show.

NCIS right out of interigation.
Tony - That's okay boss you will break her in round 2.
Gibbs - There won't be a round 2.
Tony - But boss you didn't break her!
Gibbs - Yeah I know Dinozzo, I was there.

NCIS 

The Naval Criminal Investigative Service, some of the best federal agents out there. People often assume that everything NCIS is related to the show-it's a good show, folks-but the actual agency does exist. They solve crimes and handle criminal matters related to the United States Navy and Marine Corps. They employ special agents, lawyers, forensic scientists and computer technicians, to name a few of the people that work for the NCIS.

Maddie: I just graduated from FLETC and I am now on my way to becoming an NCIS agent.
Dave: Oh, like in the TV show?
Maddie: No, as in a federal agent who solves crimes concerning the United States Navy and Marine Corps.

NCIS Marathon

Something of a daily occurance, NCIS is a great show and it seams its so great that they have "Marathon's" almost everyday. Do not get sucked in as these last for 12-24 hours and you will get nothing done.

Person 1: I'm going to work on my project *walks into TV room* EWWW!!! NCIS Marathon! *Two hours later*: Shit I got nothing done!

In short don't get sucked in.

NCIS: Los Angeles 

A television crime/drama centered around the personal and professional lives of members of the NCIS Office of Special Projects. The main characters include G Callen, the Russian-speaking Special Agent in Charge who was once a foster child, former Navy SEAL Special Agent Sam Hanna, pretty but tough Special Agent Kensi Blye and LAPD liason Detective Martin Deeks. Supporting characters are the team's boss, Hetty Lange, techies Eric and Nell and psychologist Nate. The show is a spinoff of the original Naval Criminal Investigative Service, and it was introduced in the NCIS two part episode 'Legend'. The OSP team is close they are shown to be good friends outside of work. Kensi and Callen are very close and there is a lot of sexual tension between them, much like Tony and Ziva from NCIS. There is also a semi-romantic relationship between Detective Deeks and Agent Blye, as they are shown to have a constant banter, sometimes with sexual overtones.

Robert: Wow, I started watching NCIS: Los Angeles last night. For a spinoff, it's pretty good.

Mandy: Wow, really? I heard they ripped off NCIS.

Robert: Not really. The characters are pretty different.
