For those unaware, the late George Burns and his wife Gracie Allen had a schtick where, at the end of their comedy act, George would say, "Say goodnight, Gracie", and she is supposed to have replied, "Goodnight, Gracie."
She never actually did reply this way: her reply was always simply, "Goodnight." Some other comedy troupes of the era had done this joke in the past, and apparently it stuck in the popular ethos as having been her. And so it has, apparently, for Apple's SyncServices programmers.
Don't be too harsh on them, Apple. The server had to report something, and this probably saves code over several more boring things it could have said.
