The gentleman usually credited with the 'invention' of the doughnut hole was a sea captain named Hanson Gregory. As the story has it, Captain Gregory was at the helm of his ship, eating a fried cake one night, when stormy weather arose. Gregory,needing both hands to steer the ship, spontaneously rammed the cake over one of the spokes. The reason a dog curls up with its tail covering its nose is to keep it warm during cold weather. In hotter weather they tend to stretch out to get rid of the heat.
Some dogs also tend to dig holes in cool, shaded spots to give off heat.
