Throughout its many years on television, “NCIS” has become a cr1minal procedural classic, and it’s easy to see why. For the past 19 seasons and counting, the Naval Cr1minal Investigative Service has taken on some genuinely riveting cases that have kept audiences, both new and old, tuned in week after week.

Not to mention, the characters tasked with assessing these circumstances, as well as the friendships they’ve formed with one another since the show’s debut in 2003, are immensely interesting to watch.

After departing from “JAG” and trying everything in its ability to stand on its own two feet, “NCIS” established a few cast members as series regulars.

Mark Harmon’s Leroy Jethro Gibbs is undoubtedly the most well-known, having been the program’s face for just under two decades, but he is far from the only one to have achieved icon status.

Abby Sciuto (Pauley Perrette), Tim McGee (Sean Murray), Ziva David (Cote de Pablo), and others have all achieved similar levels of popularity during their “NCIS” tenures.

Of course, it would be foolish not to include the perennially popular Dr. Donald “Ducky” Mallard (David McCallum) in this discussion. The bow-tied medical examiner has been a “NCIS” fan favorite over the years, thanks to his biting sense of humor.

According to fans of the program, this is by far his funniest line yet.

Ducky’s response to Ilan Bodnar’s rude remark was gold.

Ducky is unquestionably one of the wittiest members of the “NCIS” cast. Even while he performs autopsies and compiles psychological profiles, he manages to crack a funny one-liner every now and then. However, Redditor loki2002 believes that his response to Ilan Bodnar (Oded Fehr) in the Season 10 episode “Shiva” is unparalleled.

After being brutally asked who his grandfather is, Ducky just responds, “Well, that depends.” Who is your grandmother?

Unsurprisingly, several other “NCIS” fans joined in to share their comments on Ducky’s excellent roast. “Credit to whomever wrote that,” said Jlx_27, and the-_-seeker added, “I remember the joy I felt after seeing this scene for the first time!!”

Reddit user GoalHistoric6867 also made a remark requesting “NCIS” would do more with this answer, such as having him use it on someone who turns out to be his granddaughter, unknown to him. Esorellehcim complimented David McCallum’s portrayal of Ducky and his sassy personality.

When “NCIS” comes to an end, it will undoubtedly be a staple of pop culture for quite some time. It’s difficult to deny that Ducky and his many memorable lines won’t play a little part in that durability.
