The Guinness can that isn't moving is yours

There's a billion old Guinness ads we could post in honor of St. Patrick's Day, but we'll limit it to this responsible-drinking effort that BBDO Toronto did a couple of years back—sending bars some specially designed cans with the Guinness type all blurry along with the note, "Please don't drink and drive." It's a neat effect, though possibly the type coheres into a readable logo when you're actually smashed.
