I Did It Again...
Recognize the father in this screenshot?

Yes? No? It's from X Files... Season 1, Episode 5: The Jersey Devil. The last 10 or so seconds of the show... You probably won't get it just by looking at him. I didn't, really. It was actually his voice that made me go: "I KNOW THAT MAN!" Immediately, I guessed it might be the guy who plays Dr Bill Lee in Stargate SG-1 and Atlantis. The actor who played him was Bill Dow. If you look at the middle of his career, you see multiple appearances in X Files as a "Dr Charles Burks". Don't really remember that character, but I seem to recall him being in a few episodes when I was watching it the first time through. (Why, yes, I am, in fact, beginning my second time through the series!) But... No credit for anyone in "The Jersey Devil". Have I finally been defeated? Has my superior power of observation finally been bested? WAIT! There's a link... "3 More". He's been in three more episodes than what's listed on his main page... What does THATÂ say?
