The episode where, in one of the cut-aways, it shows a caveman and his wife and the wife is upset because she found the caveman equivalent of pornographic images in the husband's belongings (and they're just, like, stick figures or something).
Thanks for the help!
-- Evacuate? In our moment of triumph? I think you overestimate their chances.
I know it was after the initial cancellation but before I stopped watching, so it's probably an episode from Season 3, 4, or 5, and I'm pretty sure it's not from Season 3. Apologies I can't be of more help, I remember the scene just not the episode.
