I love plays on words, especially when they are used in marketing. Murray's Cheese has used an expression that many of us are familiar with, "Let's grow old together." Instead of "old", they used "mold" to represent cheese in this relationship.
I recently stumbled on a lovely thing called The German Quiz, which was a quiz to see exactly how German you are. It's quite facetious, but still hilarious, including an image of a man wearing a fanny pack and rocking his socks with sandals.
After taking the quiz, I realized that The German Quiz was a clever ploy to draw attention to a new book written by Adam Fletcher, an Englishman living in Berlin.
