No joke: This email was actually sent out to Washington Post employees:
Please refrain from watching NCAA basketball tournament games over the internet at your desk.
Although convenient, streaming video in large amounts over our network will slow response times in applications necessary for the production of the newspaper. If you happen to have a few spare minutes to root on your team or follow the bracket-busters, please use a nearby television. We appreciate your patience and support.
