If using wooden skewers, soak them in water for 15 to 20 minutes. Preheat the grill to medium-low heat. Place a marshmallow on the end of each skewer. Break the chocolate bars into 4 pieces each and place 1 piece on each of the 8 graham cracker halves. Carefully hold the skewered marshmallows over the grill for 3 to 4 minutes, or until done to your liking. Top each piece of chocolate with a toasted marshamallow, then another graham cracker half, making sandwiches. Serve immediately.

Skewers are definitely a better choice ('cause they don't add that woodsy taste of tree bark)!
