My ex used to write car commercials, and I asked her why they all had that goofy tone and all sounded the same in a weird way. I told her that I couldn't remember a single dealership from all the commercials I'd heard, since that tone lets me filter them out. She told me that was just because I wasn't in the market for a car, and if I was, that same tone would make the car commercials stand out. Sure enough, when I was in the market for a car years later, I realized she was right!
