There is SOMETHING happening on the internet! OK, so maybe that wasn't specific enough. Phil Plait of Bad Astronomy Objects, MarkCC of Good Math, Bad Math calls him on it, and I'm honestly not quite sure what they are on about. Something philosophical, I think.
What I do know is that it started off with a comment about the meaning of gravity. Silly people! Douglas Adams explained all this to us long ago!
Here is a more recent version of the story of the Sperm Whale and the Bowl of Petunias.
