Ummm. I never understood this misconception of the moon. Am I the only one to whom the dark side of the moon is visible and obvious when it's a crescent? It's dark blue against the black of space, but it's not THAT dark a blue, I don't see how you ordinary mortals can't see that much; it never looks like anything but a complete sphere to me. Possibly I'm just a monster and I can see things you can't, but even then, when do you ever see stars INSIDE the circle in the unlit portion?
Also people, people, that's not Neil. That's so obviously Buzz. Neil could never have done that.
.....Its just a shirt. Obviously he wouldn't even be able to skate on the crescent cause its not there, its a full moon all the time, so there wouldn't be any "empty" space to stand on. Its just an idea for the shirt, meant as a joke
