There was a moment in the episode when Vic and Nog were talking when I realised that a weird-looking alien was talking to a holographic 60s lounge singer, and I felt a little embarrassed by the silliness of it.
You know, it's surprising, in a way, that we don't have that reaction more often when watching these episodes. It shows you, I guess, how much our perceptions of things are determined by conventions and what we expect to see.
For example, I watched Call to Arms
not too long ago. And there's a moment where it's like: the lizard guy is annoyed with the sickly pale/strange ears/weird hair guy, and they are both wearing some sort of elaborate monocle thing that they are staring into. LoL
