A faster-than-light neutrino passes through a bar, travels out of the galaxy and near to a supermassive black hole, which flings it around. In an astonishing coincidence, this causes it to pass back through exactly the same bar, what works out to be only a few seconds earlier.
This miracle passes unnoticed by the bartender, who can’t see the neutrino and is busy discriminating against talking mushrooms and strings.
