This Christmas Vacation Shirt references the scene where Mr. Shirley and his suits walk past Clark after telling him to write a brief summary about the non-nutritive cereal varnish he is working on. Mr. Shirley tells "Bill" not to forget the report and then he and his lackeys shuffle past Clark. Clark then greets each with Merry Christmas until he realizes they aren't paying attention to him at which point he switches it to Kiss My Ass, Kiss His Ass, Kiss Your Ass, Happy Hanukkah.
