I think I saw this in a youtube video taken out of context so I'm not exactly sure when it was made, or if it was a TV show or a movie. And while it could obviously be from any time after 1980 because it references Empire Strikes Back it felt 21st century to me.

It seems to be a future post-apocalyptic setting, the power isn't on, everyone's dressed in rags, there's scavenging etc. and in a moment of down time two of the main characters act out the lightsaber duel from Empire Strikes Back to entertain the young children who live there, and the kids gasp at the "I am your father" bit.

What's this from?
