This Christmas Vacation t-shirt is designed to look like it could appear on an ugly Christmas sweater. The image shows Santa's sleigh flying over Cousin Eddie's R. V. The shirt reads That There Is An R. V. In Christmas Vacation, Cousin Eddie and his family made an unannounced visit to the Griswold house in their R. V. The vehicle appeared in one of the most hilarious scenes in cinematic history when Eddie emptied the R. V.'s chemical toilet into a sewer while he wished the Griswold's neighbors a merry Christmas and said, "Shitter was full." Christmas Vacation is one of the greatest holiday movies of all time. Everyone will know you are a fan of the 1989 classic starring Chevy Chase when you wear this Faux Ugly Knit RV Christmas Vacation T-Shirt!
