All my friends and family are tired of hearing this story, but you seem a more appreciative audience. In 2005 or so, I bought a new Ford pickup. While we were in the office finalizing the paperwork, I couldn’t take my eyes off an advertising poster on the wall announcing the arrival of the new Mustang. The tag line, in hot-rod lettering, proclaimed: You’re Wildest Dream Is Here! Below was a graphically souped up model in red. As we finished up the paperwork, I said to the salesman, “I have to say, I can’t take my eyes of this poster.” We had the following conversation:

Salesman: Oh, yeah, the new Mustang GT; 17 inch alloy wheels, 4.6 liter V-8….
Me: No, I don’t mean that. It says “you’re wildest dream.” That’s not right. It should say, “Your–Y O U R– wildest dream.” I spelled “your.”
Salesman: (puzzled and proofreading) No, that’s right. It’s got the possessive apostrophe.
Me: That’s not a possessive apostrophe. That’s a contraction of “you are.” That poster says, “You Are Wildest Dream Is Here.” That’s not right.
Salesman, (pondering) Hmmm. No, that’s right. That’s a possessive apostrophe; that’s right. I have a degree in English; that’s correct.
Me, sputtering: You may have a degree in English and I’m a homebuilder, but that’s just wrong. That slogan says: “You Are Wildest Dream Is Here.” That doesn’t make any sense.
Salesman: Well, I guess we’ll just have to agree to disagree.
To this day I regret not asking if, when they were done with the promotion, I could have the poster. As an aside, just now, wondering if such a typo was a collector’s item on eBay or something, I googled “2005 Ford Mustang You’re Wildest Dream.” Google returned: Showing results for 2005 Ford Mustang YOUR Wildest Dream. But it sounds like a collector’s item, so if any of you Internet sleuths come across that poster, I’m in the market.
