Wow, that's awesome. I can't make any of that out at all. But then, my eyes are unreliable at the best of times.

I think it's sometime in the ninth season that someone, possibly Daniel himself, says that he has three Phds. Perhaps he finished up the third one after this episode? It does seem to fanon that at least the first two were Archaeology and Linguistics, though, not Archaeology and Anthropology. And in Emancipation, he doesn't seem to be an expert in Anthropology, just has knowledge in passing, as if he took a few courses.

Ah, well.
