As I was transferring and reorganizing my phone directory, I found a half-forgotten listing for "MORON". After a moment, I recalled that entering that number and setting it to a null ring was a workaround to banish some nitwit who couldn't wrap his head around the concept that there was no "Ernesto" here, and there still would be no "Ernesto" here no matter how many times he called the same number.
While entering a calendar entry for Boskone, I noticed the lines:
Attendees: No attendees
I'm sure the concom will be terribly disappointed.
