Back in the day, when Honda was a $22 million account, they wanted to do an ad celebrating the sale of their 1 millionth car. I was lucky enough to get the assignment. There was only one hitch. The lawyer for Honda needed to see the proof that there had indeed been a million cars sold.
Skipping the obvious question that they were the ones who had told us they sold a million, I had to figure out how to make the case. And remember, this was in the days before the Internet. And personal computers. So, I took the listings of all the registrations of Hondas since 1974 and did a linear regression analysis for the remaining 6 months to project mathematically when the actual milestone would be reached. The lawyer bought the argument, and that was the only time in my many years as an Art Director that I was able to use my Statistics class training to sell an ad.
