CSI: Miami was one of the most intense shows of the 2000s, known for its gritty crime drama and pithy one-liners from its star, David Caruso, but Horatio Caine's best line has less to do with humor and more to do with the heart of the show itself. Throughout the CSI franchise, CBS worked hard to differentiate the different teams from one another. With several different shows within the franchise, CSI: Miami stood out because of Caruso's Horatio Caine, who was a seasoned investigator that made it clear he knew exactly what he was looking for, no matter the case. CSI: Miami developed its specific quirks around Caruso, who often pulled his sunglasses off his face and delivered a pithy line of dialogue upon walking up on a crime scene before the opening credits of the series, set to The Who's "Won't Get Fooled Again", blared on screen. The combination of Horatio's line, sassy sunglass removal, and the smash cut to the opening credits is just one of the iconic parts of CSI: Miami's history, but the popularity of these moments sometimes overshadowed the bigger things happening on the long-running series, which aired for 10 seasons between 2002 and 2012. While the broad themes of all the shows in the CSI franchise shows are the same, each series within the franchise has its own quirks. Horatio's best line, however, encapsulates a specific piece of what CSI: Miami stands for as a series, cutting directly to the heart of the show. Horatio Caine's Best CSI: Miami Line Isn't A Traditional One-Liner Although Horatio was always good for a quick one-liner, his best quote of the series is one that is far more memorable, a bit deep, and still, somehow, humorous. During CSI: Miami season 2 episode 9, "Bait," the team is investigating a case that finds their victim being attacked by a shark after she's already been killed. Within the episode, Detective Frank Tripp (Rex Linn), comes up as a potential suspect for the murder, which makes things difficult as the investigation continues. While Horatio knows that a member of his team wasn't involved, he has to investigate all avenues. Horatio's best line of the series, which comes toward the end of the episode, acknowledges the team element of the CSI franchise more than the character has up to that point. Speaking to Tripp after things have been resolved, Horatio explains, "In the future, if you're gonna watch somebody's back, let me know about it so I can watch yours." Taking things into his own hands, Tripp decides to move forward with an investigation of his own that isn't entirely up to standards. When things go awry, Horatio gently warns his detective not to go at things alone unnecessarily again.

Horatio's best quote is a supportive one, a line that proves that he has his team's back no matter the circumstance as they move through incredibly dangerous situations. This encapsulates one of the biggest themes of the franchise as a whole, sharing the philosophy that even in tough moments, none of the CSI team members should have to be on their own. CSI: Miami sometimes receives less critical attention because of Caruso's more humorous moments as Horatio, but it aligns with the rest of the universe in a way that makes it clear that it's a big piece of the puzzle. The series remained successful for a decade with its pithy dialogue and interesting cases, but the teamwork at the heart of the series is what kept viewers coming back for more week after week. Horatio became an enduring part of the series because the CSI: Miami team knew that even in the most difficult circumstances, they had each other's backs. Release Date 2002 - 2012-00-00 Network CBS
