@Markerrag -- why bother? Some people like to buy them with shells because they suck on them. You will find that method used by a lot of people trying to kick a smokeless tobacco habit.
What is fun to watch is how sunflower seeds have replaced smokeless tobacco in baseball in a lot of ways. It used to be common to see big league ball players spitting tobacco. These days they tend to spit seeds. It's still a nasty habit, but it is less likely to lead to cancer.
