Carefully remove the thin sugar shells from the beer nuts and set aside. Heat 2 inches of water to simmering, not boiling, in the bottom of a double boiler. Place the chocolate in the smaller pot and set it over the simmering water. Stir until the chocolate melts. When the chocolate is melted, remove the small pan from the heat. Carefully insert a toothpick into each pretzel nugget, then dip the nugget into the melted chocolate. Be sure your pretzel (toe) is completely covered. Place 1 sugar shell (toenail) on the end of each toe. Place on waxed paper to cool and repeat with as many toes as you desire. Makes 4 to 6 feet.
