Homer took his family to a holiday trip to the cabin where Henry K. Duff invented the Duff Beer. Homer found there a tape of Duff where he told that in his search of a beer, he discovered something truly frightening. When the Beer recipe is read aloud the ancient evil awakens spirits that have possessed his wife and children and he warned the listener not to read the recipe for Duff Beer aloud before he started to scream and the recording ended. Homer then found the recipe book and read it aloud. Meanwhile, a green glob appears from the ground outside the cabin.
