The 15 Best 'O.C.' Season 1 Moments That'll Make You So Nostalgic For The Show's Early Days

Warner Bros. TV

The O.C. turned 15 in early August, and the anniversary is the perfect reminder of how amazing the show's first season still is. Even though the second and third season are also full of memorable dramatic arcs, the first season of The O.C. is special to fans thanks to all its iconic moments, from Luke’s “Welcome to the O.C., bitch!” to the beginning of the show’s biggest romances. When it first aired, it was an excellent intro to characters that fans instantly fell in love with and proceeded to follow for four seasons.

The great thing about the O.C.'s first season is that it has 27 episodes, so it feels like two seasons in one — making it the perfect one to marathon. It has plenty of twists that fans could have never expected (Julie and Luke’s affair! Theresa’s pregnancy! Marissa’s scary experience in Tijuana!). But it also has so many touching moments that makes it easy to relate to the characters as they struggled with first relationships, family issues, teen angst, and so on. Plus, this season truly has it all: steamy affairs, love triangles, teen pregnancy, road trips, huge fights — and even an appearance by Paris Hilton. Take a trip down memory lane and revisit the first season’s best moments.

Many bands played The Bait Shop throughout the show, but Rooney was the first to get its own episode centered around it. Even though Rooney didn't quite retain the success of other bands from the show like The Killers, Modest Mouse, and Death Cab For Cutie, the episode perfectly encapsulates the time that The O.C. was on air.

There is so much that goes on in this episode, from Paris Hilton flirting with Seth to Summer having to deal with the star from her favorite TV show The Valley being a total creep. It showed how even though no trip is as dramatic as Tijuana, the gang's road trips are always eventful.

15The Vegas Trip

But even more eventful than the L.A. trip is the one to Las Vegas, where Seth learns the ultimate lesson on the consequences of his crappy actions.
