Very big news out of CERN - the Higgs boson has been discovered - or I guess more correctly - the Higgs boson has been scientifically detected. This is very big news for science but probably my last chance to repeat this joke:
The Higgs boson walks into a bar. Bartender says, "What's the matter?" "Exactly."”
EDIT:
Stephen Hawking's reaction to the news is beyond awesome.
