“Astrophysicists stripped Pluto of full planethood.”
“An entire blog (laurele. livejournal.com) arose to restore Pluto's planethood.”

“From a story in today's NYT on evolving definitions of planethood:”

“(Given how upset people got when Pluto was demoted from planethood, I can't wait to see how they'll react to Mars's exile.)”
“We are meant, first of all, to be citizens of earth with all the love and responsible behavior that is required to be a hologram of planethood, one of Earth's human brain cells thinking planet-thoughts.”
