I was talking to Three Dog, and when I asked about his parents, he said "Parents? Ha! I was born of the desert and have sand in my veins!"

I thought this was really interesting, since in Skyrim, Nazir (who is voiced by the same person as Three Dog) is a Redguard. Redguards live in Hammerfell, which is a desert.

Coincidence? Easter egg? I don't know. I know that Skyrim began development after Fallout 3 came out, but Three Dog's line doesn't really make sense otherwise.
