For me at least, the Metier d'Art extravaganza staged by Chanel at Linlithgow Palace on Tuesday night was such an event: a work of theatre that will linger long after the fashion circus has moved on to the next big thing.
And then there are others, such as one who was featured on NPR's "All Things Considered" last night - a fellow down in South Carolina - professor - who blithely assured us that terror is something that will send you straight to hell.
It's not clear why there was sucha sense of urgency to get it out, but the fact that it came to light on Tuesday night when Obama was steamrolling Clinton in Virginia, Maryland and the District of Columbia has some conspiracy-minded bloggers making all kinds of assertions.
