Maybe it's just because I love crossword puzzles, but this ad from Starbucks was really clever. It ran on the puzzle page in The Times in the UK. Given that the sort of person who might hang out in a coffee shop is also the sort of person to pass the time doing the newspaper crossword, this is a really clever idea. The ad asks you to find the 25 countries the company sources to find Arabica coffee beans. Just glancing over it, I found "Yemen" and "El Salvador" I would have circled more, but the black marker is making it hard for me to see my screen.
