Huey lists the symptoms of the fried chicken flu while Tom experiences those exact symptoms in the background, mimicing the scene with Dr. Rumack and Captain Oveur.
When the Woodcrest Fried Chicken Flu Militia shows up to demand the food and water that Huey has stashed away in his house, one of the Militia Members is dressed like Lord Humungus with face mask and bare-chested leather straps.
As the Freeman family escapes the house with their food and water tied on top their car, Aunty Entity's hairstyle and large earrings are worn by the Woodcrest Militia leader as she orders her gang to get on a school bus to give chase.
