I didn't realize until long after listening to the song and then seeing the episode that the title came from a Star Trek episode. I remember seeing Greg wearing a Star Trek shirt and I've read about him talking about a bizarre episode he saw but never anything about the connection with the song title. Cool line to pick for a song name.
By complete coincidence, I was watching an old original Star Trek episode the other day, and flipped out when one of the characters said "Behold a marvel in the darkness". I figured it had to be a common reference, but Google turns up nothing but Deerhoof and Star Trek. Guess they're nerds.
