i once had a little bag of crackers i got at a restaurant for my soup and it had a diagram and a warning on it. The diagram was of a person opening the crackers and them going into there eyes. The second part of the diagram was a car in the ditch. The warning said "Do not attempt to open while operating vehicles, Small particles could make there way into your eyes and impede your vision" i thought that it was funny to see on my crackers.
