My uncle is so excited! He found an original twelfth century book about the kings of Iceland. He wants to tell me all about it.

Ever since he came back (and he thinks he never left), Grauben has been talking to him about "Euhemerism" and "Eddas" and gods and I have no idea what they are talking about. Or what it has to do with Martians. Grauben is out of the house right now. Should I let Uncle bore me for hours? Or do something else?
