NOW THAT PLUTO GOT DEMOTED to dwarf planet, some people have viewed this change as the end of the world as we know it, apocalypse, ragnarök, TARFU (military slang for "totally and royally f***ed up").
For instance the renowned obsolete mnemonic,
My Very Efficient Method Just Summed Up Nine Planets
has now become the broken:
My Very Efficient Method Just Summed Up Nine, minus one.
As for the planet represented by the U in Up, its name (not to evoke anuses or urine, as I have previously explained), should be pronounced oo-RAH-nus.
