This Christmas Vacation t-shirt shows Clark W. Griswold, with a surprised look on his face as the Christmas lights on his house finally lit up when he plugged them in. In Christmas Vacation, Clark Griswold hung Christmas lights, 250 strands composed of 100 lights each on his house. Each time he plugged them in, nothing would happen. It was Clark's wife, Ellen that flipped a switch and saved the day as the all the lights turned on...even though the little lights weren't twinkling. 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 Hallelujah Christmas Vacation T-Shirt!
