You want to know the real meaning of Christmas? It's Saturnalia, a Roman pagan holiday that celebrates the winter solstice. So, wear this tshirt to spread the good news: You don't have to buy Christian religious baggage to celebrate Christmas. Just say, Happy Saturnalia!
You can be happy without guilt, too, because this t-shirt is made in the USA, not in some nasty overseas sweatshop of the sort where most Christmas trinkets are manufactured.
