Transcript
- Luna: So there's this moment in copywriting lore that I think about often — the Old Spice 'Smell Like a Man, Man' campaign. It's this cultural juggernaut, right? But it almost never saw the light of day. Lucas: Right. And the reason it almost died is almost too perfect for this show. It wasn't the concept, it wasn't the budget, it wasn't the client's cold feet. It was one sentence. One specific line in the script that focus groups hated so much that the whole thing almost got shelved. Luna: One sentence. That's wild. What was the line? Lucas: The original script had the actor, Isaiah Mustafa, say something like — and I'm paraphrasing from memory — 'I'm on a horse, and I'm wearing a towel, and I'm holding a bottle of Old Spice. You don't need to know why.' The last part — 'you don't need to know why' — that's the line. The agency, Wieden+Kennedy, wrote it as a kind of cheeky non sequitur. They thought it was funny. The focus groups hated it. They said it felt condescending. Like, 'the brand is telling me not to ask questions.' Luna: Huh. So the very thing that made it quirky — the unexplained absurdity — is what almost killed it. That's a really delicate line. Lucas: Exactly. And if you've been listening to this show, you know that copywriters are always chasing the 'curiosity gap' — you dangle a mystery, you don't explain everything, you make the reader lean in. But this is a case where the curiosity gap backfired because it felt like a wall, not an invitation. The audience didn't feel curious. They felt talked down to. Luna: So how did they fix it? Lucas: They cut the line. Completely. They replaced it with nothing. The final script just has Mustafa riding the horse, listing benefits, and then a simple 'Smell like a man, man.' No explanation, no wink. The absurdity was still there, but the condescension was gone. And they shot that version in about 48 hours because the original shoot date was approaching and the client was ready to pull the plug. Luna: So the fix wasn't rewriting the line. It was deleting it. That's brutal — I bet someone at the agency loved that line. Lucas: Oh, absolutely. And that's the real lesson here. Great copywriters learn to kill their darlings. The line that the writer thought was clever — the whole 'you don't need to know why' — it was a darling. But the data said it was hurting the response. So out it went. Luna: And if these kinds of marketing breakdowns have sparked something you've actually used in your own writing — a headline tweak, a tighter subject line — this is the part where we mention that listener support is what keeps this show free of ad breaks. If you've got a buck or two to spare, you can toss it our way at buy me a coffee dot com slash fexingo. No pressure, no guilt. Just a coffee if the show's been worth it. Lucas: Yeah, and we mean that. We don't do sponsors, we don't do mid-roll ads, and the only reason that works is because of the people who chip in. So thank you to anyone who's ever done that. Now — back to that fatal sentence. The Old Spice fix is famous, but it's not the only example of a single line nearly sinking a campaign. There's an older one from direct mail that I think is even more instructive. Luna: Let me guess — 1950s, a fat mailing, a subhead that killed the response. Lucas: You know me too well. So there's this mailing from a publisher — I believe it was Rodale, the health newsletter people — and they were testing a control that had been working for years. The control had a fairly long subhead under the main headline. Someone on the team — probably a junior — suggested they shorten the subhead to make it punchier. They cut it from about twelve words down to six. The test flopped. The six-word version underperformed by something like 40 percent. Luna: Forty percent? That's millions. What was the subhead? Lucas: I don't remember the exact wording, but the original had a specific benefit — it named the condition the newsletter addressed. The shortened version was more vague, more clever. It sounded better. But it didn't sell. The readers needed that concrete signal, that anchor. Without it, they didn't see themselves in the offer. Luna: So one sentence — or sub-sentence — can either make or break a campaign in either direction. The Old Spice example shows you a line that needed to die. The Rodale example shows a line that should have stayed. Lucas: Exactly. And that's what makes copywriting so hard — and so fun. There's no formula that says 'short is better' or 'long is better' or 'clever is better.' It's always about what the specific audience needs at that specific moment in the reading experience. The Old Spice audience needed to feel included, not mystified. The Rodale audience needed to feel recognized, not entertained. Luna: So how do you know which one you're dealing with? I mean, if you're writing a headline or a subhead today, how do you avoid accidentally writing the line that kills your campaign? Lucas: You test. That's the honest answer. But you also need to read the feedback correctly. In the Old Spice case, the focus group didn't say 'we don't get it.' They said 'it feels condescending.' That's a different signal. If they'd just said 'we don't get it,' the team might have rewritten the line to be more explanatory. But because the signal was emotional — they felt talked down to — the right response was to remove the source of that feeling entirely. Luna: Right. The audience told them exactly what was wrong. They just needed to listen. Lucas: And that's the discipline. The easy thing is to argue with the data. 'But it's funny.' 'But it's clever.' 'But the client already approved it.' The hard thing is to say, 'The data says this doesn't work. Let's try something else.' And sometimes that means deleting the line you were most proud of. Luna: I think there's a parallel here with the Caples episode we did — Ep 10, where he talked about how the headline is the most important thing. But even Caples would say that the headline isn't the headline if it doesn't work. You can't just write a clever headline and assume it'll sell. Lucas: Absolutely. And Caples himself was famously rigorous about testing. He'd test one word changes. He'd test different emotional appeals. He understood that the headline is the gatekeeper. If the gatekeeper alienates the reader, the rest of the letter doesn't matter. And that's what happened with Old Spice — 'you don't need to know why' was a gatekeeper that said, 'This isn't for you if you want an explanation.' The audience wanted an explanation. So they left. Luna: Or they felt annoyed. Which is worse than leaving — they might remember the brand negatively. Lucas: Exactly. And that's the hidden cost of a bad headline or a bad line. It doesn't just fail to sell — it can damage the brand's relationship with the customer. Old Spice got lucky because they caught it in testing. But imagine if they'd gone to air with that line. The campaign might have been remembered as 'that condescending Old Spice ad' instead of the iconic thing it became. Luna: So one sentence can change the entire trajectory of a brand's campaign. That's powerful and terrifying. Lucas: It is. But it's also liberating, I think. Because it means you don't need to rewrite the whole thing. You don't need a new strategy. You don't need a new creative director. You just need to find the one sentence that's causing the friction and fix it. That's a much smaller problem to solve. Luna: So when you're reviewing your own copy — whether it's a sales letter, a subject line, a landing page — what's your process for finding that one sentence? Lucas: I read it aloud. Then I read it again, but this time I imagine I'm a skeptical customer — not a friendly one. And I look for any sentence that makes me pause, or that feels like it's trying too hard, or that makes me feel like the writer is showing off. That's usually the candidate for the knife. Then I ask: if I delete this sentence entirely, does the copy still make sense? If yes, I delete it. If no, I rewrite it with less ego. Luna: That's a good heuristic. 'Less ego.' I think a lot of copy problems come from the writer wanting to be clever instead of wanting to be clear. Lucas: Exactly. And clarity doesn't mean boring. Look at the final Old Spice script. It's absurd — a guy on a horse, on a boat, with tickets to that thing you love. It's not boring at all. But it's clear. Every line moves the viewer toward the product. The 'you don't need to know why' line was a detour. A clever detour, but still a detour. Luna: So the takeaway for today: test your lines, listen to the feedback, and don't be afraid to cut your darlings. And if you're a listener who's ever caught a bad line before it went live — you know that feeling. Lucas: Yeah, that feeling is the best. And the worst. But mostly the best. So go look at your current project — the headline, the subhead, the call to action. Read it aloud. Ask yourself: does this line help the reader say yes? If not, kill it.
