Well, we have a winner for our little quiz from last week. "don digiovanni" knew that the "Koka Kola" mentioned in the post title is also the name of a Clash song. Actually, I'm guessing that "don digiovanni" knew how to Google "Koka Kola" and that's how he came up with the answer. What he didn't mention in his comment was the real point of the title, which is that the song includes a cynical line about advertising: "I get good advice from the advertising world." We'll go ahead and give him credit anyway.
OK, I promise my next quiz won't be related to Clash lyrics.
