WilliamsWe were only 18 words into that exchange when you realized one of the characters owns, or manages, a plumbing company. You figured that out even though the character never said it.You walk into the middle of conversations every day and quickly figure out what’s happening. When you’re writing banter in advertising, you must allow your audience to do the same.And did you notice that neither character said “WTF?” It was you that said WTF after the plumbing company owner said, “WATER… TANK’s… FINE.” That was the moment you participated in the ad. Marketers like to call this “engagement,” but a more accurate word is “participation.” You want your readers, listeners, and viewers to participate in your ads by filling in what you left out.Is the manager of the plumbing company really that dull-witted, or is he just having fun with his friend? You’ve got to figure that out for yourself.Are you beginning to see why well-written banter is difficult to ignore?Ad campaigns built around the banter of memorable characters never get old. Instead, they get stronger with each passing year.You won’t learn to write banter by studying advertising. Instead, you must study screenwriters and novelists.This passage from Sea Swept, by Nora Roberts, is a good example:CAM: You can’t buy decent socks for twenty these days.ETHAN: You can if you don’t have to have some fancy designer label on them. This ain’t Paris.CAM: You haven’t bought decent shoes in ten years. And if you don’t pull up that frigging seat, I’m going to –PHILLIP: Cut it out! Cut it out right now or I swear I’m going to pull over and knock your heads together… I’ll dump your bodies in the mall parking lot and drive to Mexico. I’ll learn how to weave mats and sell them on the beach in Cozumel… I’ll change my name to Raoul, and no one will know I was ever related to a bunch of fools.SETH: Does he always talk like that?CAM: Yeah, mostly. Sometimes he’s going to be Pierre and live in a garret in Paris, but it’s the same thing.The best advice I can give you about putting banter in ads is this: Don’t start writing until your characters have come fully alive in your mind. You’ll know this has happened when one of them says something unexpected.Write that down. And then listen to what the other character says in response.If you ever force an imaginary character to say what you wish they would say, that character will immediately die and your ad will sound like an ad.Worse than that, the rotting corpse of your dead character will make your ad smell like an ad. So trust your characters to know their jobs. Sooner or later one of them will
