Since Friday’s ad is number 33, I thought it only appropriate to feature one for Rolling Rock, since they so successfully exploited the mystery surrounding the number “33” being printed on their bottles, though the likeliest story isn’t that mysterious. This humorous ad plays on that theme with some of history’s greatest thinkers contemplating the mystery, which they call “Great Theories of ’33.'” The bottom row is Charles Darwin, Ludwig Van Beethoven and Thomas Edison. The top row is Sigmund Freud, Galileo and William Shakespeare. Also, the painting is called “Great Minds Drink Alike,” which is a pretty great name IMHO.
