I used to live with roommates and we'd occasionally walk around in our underwear. Sometimes I would walk around in my underwear with my pants around my ankles. It was hilarious how uncomfortable they would get, even though I was wearing more clothes.
The socks imply being dressed without actually concealing anything, so someone wearing only socks isn't just naked but rather naked while intending not to be. It's like how lingerie is somehow more revealing than plain nudity.
This is the only shows I’ve watched several times all the way though season 1 to the end. Very re-watchable. Like Seinfeld or the office is for some people.
It’s also the perfect show to watch on an airplane. Very easy to pick up and watch.
