As unaccustomed we are to this...
Peter Stearns, the provost of George Mason University reportedly sent the following email to his faculty today.

Dear Colleagues,

As you know, lots of our undergraduates had an exciting time yesterday in response to the basketball victory. Without in any way wishing to distort our priorities, I write to urge a bit of leniency in response to any absences from undergraduate classes today. Thanks for your understanding.

Peter Stearns

I like the phrase "exciting time yesterday" because I appreciate understatement.
