Previous to my current publications job, when I was working for a commercial printing company, I was out in the paper storage section of the press room, looking for some stock for a print job I was doing for myself. I found a ream of stock with the color name of "Dorian Gray" and was chuckling about it. My boss, the owner of the company, asked what was so funny -- he had never heard of the novel, nor probably of the author Oscar Wilde. (Probably never saw the film, either, as most of it was black and white. Sigh.)
About twenty years previous to that (at a different commercial printer), I quoted the line from the original "Little Shop of Horrors" film --
Audry Fulquard: "You're gonna be another Luther Glendale." Seymour Krelboin: "Pasadena." Audry Fulquard: "Burbank."
And only one other person (an older man working in bindery) out of 12 knew who Luther Burbank was.
