"We don't serve faster-than-light neutrinos here." said the the bartender. A neutrino walked into the bar.
Here's the article where I read that btw:
Particles Faster Than the Speed of Light? Not So Fast, Some Say

“Does E still equal MC squared?”
So asks the Irish band the Corrigan Brothers in a new song, “Einstein and the Neutrinos,” that is the latest rollicking riff on news that shocked the scientific world last month.
A group of physicists from Italy claimed they had observed the subatomic particles called neutrinos traveling faster than the speed of light. That, of course, is the cosmic speed limit declared in Albert Einstein’s theory of special relativity in 1905.
If they are right — and the jury is still out — Einstein might have some explaining to do. Among other things, a neutrino or anything else that went faster than the speed of light could go backward in time.
