In 1992, James May was tasked to compile Autocar's Road Test Year Book, which was a series of car reviews with the first letter of each beginning with a large red initial. As he felt that the work was extremely boring, James arranged and edited the first few reviews so that their initials spelled "Road Test Year Book". However, he also arranged the other reviews such that, when proper punctuation is added in, their initials spelt "So you think it's really good, yeah?

The latter was probably the reason why he was dismissed from the magazine after it went to print and readers started calling up the magazine thinking there might be a prize for being Genre Savvy.
