Watch 'NCIS'' Action-Packed Barroom Brawl Online

Bottles fly, chairs are smashed and men get kicked in places that send them to their knees in the upcoming Christmas episode of "NCIS." It won’t air until December, but ET has a sneak peek at how the brawl was shot with series stars Michael Weatherly, who plays Special Agent Anthony DiNozzo, and Cote de Pablo as Ziva David. "This man puts his hand on [Ziva's] shoulder. She doesn't like it when people touch her. She goes off. I thought it was mostly her fight, but what goes on involves DiNozzo and trying to survive," Cote tells ET. Even though Ziva knows how to defend herself — as a former Mossad agent, she knows a form of martial arts known as Krav Maga -- DiNozzo jumps into the fight.
