Earth suffers a temporary glitch in the space-time continuum, creating sentiant walruses who understand us all too well even though they have seen every episode of Firefly and might be overpowered by a bunch of Elvis impersonators but a priest tells them about the God and they are turned into weird rocks that all look suspiciously like either Elvis or Madonna, but nobody can agree on which one it is.
The End.
