Great talking point at parties, for people who're familiar with the series or not. The Greyjoy sigil looks like a uterus, but aside from that the conversation is usually pretty clean. There's something manly about picking up a beer tankard off of a coaster with the head of a direwolf or a dragon or a lion on it. Not so much the squid-uterus, but that's okay, you can assign certain coasters to friends based on their importance. If one of your friends is a lion, give them the Lannisters. If one is a wuss, give them the uterus.
