The moon + The nose

"The moon is made by some lame cooper, and you can see the idiot has no idea about moons at all. He put in a creosoted rope and some wood oil;and this has led to such a terrible stink all over the earth that you have to hold your nose. Another reason the moon is such a tender globe is that people just cannot live on it any more, and all that's left alive there are noses.This is also why we cannot see our own noses - they're all on the moon."(from Diary of a Madman)
