Joe Cortese tries to explain the Earth concept of "pajamas" to Maryam D'Abo, an alien who wants to sleep naked, in this scene from Something Is Out There. (It's just barely work-safe. Probably.)
Now I know why so many people said they remembered this show the other day. It's hard to believe this scene was televised on NBC in 1988, given how many times D'Abo comes within a hair's breadth of showing her lunar modules. I love the part where she says, "We've already seen each other's hands. What else is there to see?"
