Slap Happy Gibbs
NCIS Special Agent Gibbs is a tough and stern leader who doesn't shy away from disciplining his subordinates, especially the mischievous and attractive Agent DiNozzo, played by Michael Weatherly. Gibbs is well-known for giving DiNozzo a quick smack on the back of his head whenever he needed to put him in his place.
But it turns out that these head smacks were not the brainchild of the show's writers. They actually started when Mark Harmon, who plays Gibbs, got frustrated with Weatherly during filming and jokingly smacked him on the head. This impromptu act was so in line with their characters that it became a running gag throughout the show. Fans of NCIS have come to love and expect these head smacks, which have become an iconic part of the show's legacy.
