That's def a good point. I remember some time ago I heard the reason they didn't give them space suits/helmets was because it would inhibit their facial expressions which makes sense. Reminds me of Sheen asking Jimmy why they don't have to wear helmets in space and Carl starts singing when Jimmy answers. Guess we'll never know!
I loved that. Lampshade the inaccuracy, make it into a joke, then move on. They didn't even shrug it off as "this takes place in a universe where these aren't necessary", they were like "it's incorrect and we give -10 fucks about it"
