I LOVE this! I want to steal this idea for my hubby and me.For many years I was in a small group of employees who would sing Christmas carols in our company's buildings during lunch hours in December. I began to accumulate a LOT of Christmas shirts and sweaters. None I would classify as ugly, but lots were silly. We no longer sing, but I pull down the plastic bin the day after Thanksgiving, and can wear a different Christmas shirt every day between T'giving and Christmas.
This year, MRChristian has joined the fun. I bought us plain red long-sleeved pullover shirts at Hobby Lobby. Then I got iron-on letters. His says, "NICE" . . . mine, or course, says "NAUGHTY" . . . people always smile when they see us, and we frequently get comments. Santas usually tell him, "I'll see YOU on the 25th." They look at me and say, "Not Again!"
BTW, if you're going to be flying over the holidays, be careful when going through the TSA checkpoint while wearing a shirt that screams "NAUGHTY." TSA agents will look at you twice. ;-)
