Duke Cannon Homemade Eggnog big ass brick of soap  Every year Duke Cannon aims to make holiday spirits bright for his guests before they roll into town. Dragging the decorations down from the attic, scaling the roof to string lights across every eave and dormer, and finally, preparing his homemade eggnog — this being the annual favorite of his brother-in-law Gary, who usually ends each night of his over-extended stay with multiple helpings of no egg, no nog, just a two-finger pour of brandy.
