On an IBM boondoggle, I heard Carl Sagan expound on it at Century Plaze Hotel (LA, CA) in 1974. He was funny and good at it. One of those things one will not forget.
He showed a slide of a bogus star chart as seen from an inhabitted planet which included our sun in the constellation the locals call the Unicorn. Our sun was at the unicorn's anus. Brought the house dowm.
