So, you’re looking for the did we just become best friends song. It’s one of those things where you can hear the line in your head perfectly—Will Ferrell’s wide-eyed enthusiasm, John C. Reilly’s deadpan realization—but the music behind it? That’s where things get a little fuzzy for people.
Here’s the thing: people often get confused about whether there even is a song playing during that specific line in Step Brothers. If you’re thinking of the legendary "Did we just become best friends?" "Yep!" "Do you wanna go do karate in the garage?" "Yep!" sequence, there actually isn’t a pop song blasting in the background. It’s mostly underscore. But the reason you’re searching for a song is likely because of the montage that follows, or perhaps the iconic "Por Ti Volaré" scene, or maybe even the massive wave of TikTok remixes that have turned that dialogue into a literal anthem.
Movies like Step Brothers don't just exist as films anymore. They're audio blueprints for the internet.
The Music That Defined Brennan and Dale
When we talk about the did we just become best friends song, we have to look at the "Best Friends" montage. After the karate-in-the-garage agreement, the movie cuts to a sequence of the two grown men becoming inseparable. The track playing there is "The Longest Pee" by Derek Kelly, which is a quirky, upbeat instrumental that perfectly captures the "arrested development" vibe of the characters. It’s playful. It’s immature. It sounds exactly like what two 40-year-olds living at home would feel like while building a bunk bed.
But let’s be real. Most people asking about the music are actually thinking of "Aiaiai" by Masa. This is the song that frequently accompanies the "Best Friends" dialogue on social media. Or, they're thinking of the "Prestige Worldwide" era tracks.
The movie's soundtrack is a weird, beautiful mix. You've got Daryl Hall & John Oates’ "You Make My Dreams (Come True)"—the ultimate "feel good" track—and then you have the high-brow/low-brow comedy of Andrea Bocelli’s "Con te partirò" (Time to Say Goodbye), or rather, the "Por Ti Volaré" version performed by Will Ferrell himself at the Catalina Wine Mixer.

Why the Dialogue Functions Like a Song
In the age of TikTok and Reels, dialogue is music. The "Did we just become best friends?" exchange has been sampled, pitched up, slowed down, and layered over Lo-Fi beats more times than anyone can count. It has a rhythm.
- "Did we just become best friends?" (The Hook)
- "Yep!" (The Beat Drop)
- "Do you wanna go do karate in the garage?" (The Verse)
- "Yep!" (The Chorus)
It's essentially a pop song structure. If you’ve heard a version with a heavy bassline or a synth-wave background, you’re likely listening to a user-generated remix rather than anything on the official 2008 soundtrack.
The Cultural Weight of a 2008 Comedy
It’s kind of wild that we’re still talking about this. Step Brothers came out in 2008. The iPhone was barely a year old. Twitter was a baby. Yet, the did we just become best friends song search query remains high. Why?
Adam McKay and Will Ferrell tapped into something primal about male friendship. It’s that instant "click" when you realize someone else shares your specific brand of weirdness. Music is the shortcut to that feeling. When the movie uses Joe Esposito’s "You're the Best" (famously from The Karate Kid), it’s leaning into that 80s nostalgia that fuels the characters' entire personalities. They aren't just friends; they're a montage.
Honestly, the soundtrack is a masterclass in irony. You have Guns N' Roses "Sweet Child O' Mine" being sung by a family in a car—a scene that became so famous it arguably rivals the "Best Friends" scene for the most quoted moment.
Finding the Specific Remix You Heard
If you’re on the hunt for a specific version you heard in a meme, check these common culprits:
- The "Karate in the Garage" Phonk Remix: Very popular in gym edits. It takes the dialogue and puts a distorted, high-energy beat behind it.
- The Lo-Fi Study Version: Usually features the "Best Friends" line at the very beginning of a chilled-out track, used to signify a "vibe shift."
- The Original Score: Composed by Jon Brion. He’s a legend. He did Eternal Sunshine of the Spotless Mind and Punch-Drunk Love. His work on Step Brothers is actually quite sophisticated, which is part of why the comedy works so well. It treats the characters' idiocy with musical dignity.
Jon Brion’s involvement is actually a huge "if you know, you know" fact. He brings a level of melancholic whimsy that makes the bonding scenes feel genuine, not just slapstick.
The Catalina Wine Mixer Factor
We can't talk about the music of this movie without the climax. When Will Ferrell sings "Por Ti Volaré," it's a genuine vocal performance. He’s not just joking around; he’s actually singing. This is a huge part of why the movie stayed in the public consciousness. It ends on a musical high note that is both ridiculous and oddly moving.
Many people searching for the did we just become best friends song end up sticking around for the opera. It’s the ultimate payoff. It’s the moment the "best friends" prove their bond to the world through the power of a Spanish-language cover of an Italian crossover hit.
How to Use This Audio for Your Own Content
If you're a creator trying to find this audio to use, don't just search for the song. Search for "Step Brothers Karate Dialogue" on your platform of choice.
Most people make the mistake of looking for a licensed track. You won't find the magic of that scene in a 3-minute Spotify song. The magic is in the silence between the words and the sudden burst into the next activity.
- For high-energy edits: Look for the Phonk or Trap remixes of the dialogue.
- For "wholesome" content: Look for the clips that use the Hall & Oates track immediately after the dialogue.
- For irony: Use the original Jon Brion score, which is titled "Brennan and Dale" on most streaming platforms.
The did we just become best friends song isn't just one track. It's a whole aesthetic of late-2000s absurdity that has managed to outlive almost every other comedy of its era.
Actionable Steps for Music and Movie Buffs
To truly capture the vibe of the "Best Friends" moment in your own life or content, stop looking for a single MP3.
First, identify the version you actually like. If it’s the movie version, you’re looking for the Jon Brion score. If it’s the "vibe" version, you’re looking for Hall & Oates.
Second, understand the timing. The reason that scene works is the "Yep!"—the immediate, no-hesitation agreement. If you’re editing a video, the music should hit exactly when the second "Yep!" happens.
Third, explore Jon Brion’s discography. If you like the quirky, instrumental feel of the Step Brothers score, his work on Lady Bird or I Heart Huckabees will be right up your alley.
Finally, if you just want to listen to the song that defines the ending of their friendship arc, go put on "Boats 'N Hoes." It’s the "Prestige Worldwide" anthem that, let’s be honest, is the real song we all have stuck in our heads anyway.
The "Best Friends" moment is a cultural touchstone because it represents the pure, unadulterated joy of finding your person. Whether there's a chart-topping song playing or just the sound of two guys breathing heavily after a fight, the "music" of that scene is the chemistry between Ferrell and Reilly. Go watch the garage scene again. It’s shorter than you remember, but it hits harder every time.
