One or more of the bright sparks in filing thought it might be fun to play a practical joke on the helpdesk boys (who work a paper-thin wall away from me). So they replaced their lightbulbs with Christmas lights and wound tinsel all around their desks. And put a disco medley of tacky holiday songs on auto-repeat. This lasted for a whole hour before one of the helpdesk boys got back and, well, fairly much exploded amidst cries of "My little island of sanity has been desecrated!"
Never mind them. By about the fourth snippet of "Winter Wonderland" I had made my decision.
If I ever find out who's running the alleged "War against Christmas", I'm going to join up.
