In this hilarious sequel to Greater Tuna, it’s Christmas in the third-smallest town in Texas. Radio station OKKK news personalities Thurston Wheelis and Arles Struvie report on various Yuletide activities, including the hot competition in the annual lawn-display contest. In other news, voracious Joe Bob Lipsey’s production of A Christmas Carol is jeopardized by unpaid electric bills. Many colorful Tuna denizens, some you will recognize from Greater Tuna and some appearing here for the first time, join in the holiday fun. A Tuna Christmas is a total delight for all seasons.
