A litle physics humour to mark Professor Peter Higgs's Nobel Prize (shared)

A Higgs Boson walks into a Catholic Church one Sunday morning. The priest looks up from the altar, sees the boson, points to the sanctuary door, and yells, "We don't allow your kind in here!"
The Higgs Boson protests, replying, "But Father! You can't have mass without me!"


Thanks to Craig at Is The BBC Biased for that.
