The NCIS cast has been the subject of many fan theories and internet jokes, especially when it comes to their off-screen relationships. The popular “Siblings or Dating?” meme has even been applied to some cast members, as fans speculate about their close friendships and on-screen chemistry. While most of the cast maintains professional relationships, their strong bonds often lead to playful rumors and speculation among viewers.

Beyond their friendships, some NCIS actors have shared quirky personal interests that might surprise fans. Brian Dietzen (Dr. Jimmy Palmer) has expressed a fascination with medical oddities, while Pauley Perrette (Abby Sciuto) is known for her love of forensic science and gothic subcultures, even outside the show. Meanwhile, Mark Harmon, despite playing the rugged Gibbs, has an unexpected passion for carpentry and restoring classic cars. These unique hobbies add an interesting layer to the actors behind the beloved characters.

While no truly bizarre “fetishes” have been publicly revealed, the NCIS cast certainly has its share of eccentricities. From David McCallum’s (Ducky Mallard) deep knowledge of forensic pathology to Wilmer Valderrama’s love for extravagant fashion, the actors bring their own quirks to the table. Whether it’s unusual hobbies, unexpected friendships, or fan-fueled conspiracy theories, the behind-the-scenes world of NCIS is just as intriguing as the cases they solve on screen.
