One Christmas special you don't preempt

Once, in the early '90s, a local network affiliate made the mistake of preempting A Charlie Brown Christmas.  After viewers complained, the station rescheduled it for Christmas Day at 11 a.m.  Of all the specials to preempt...It still surprises me that any station would dare to preempt a special with so much heart and great music that speaks to so many viewers.  Unless there's a major news event, it's unwise for any station committed to airing A Charlie Brown Christmas not to show it.
