Phrase of the Day

It's several years old but with the Comcast news, the commentariat is distinguishing between on demand programming and appointment based programming. On NBC news tonight Brian Williams made a jocular reference to appointment-based news. Of course with Tivo, everything is on demand so for many of us appointment-based TV hasn't existed for years. But it's a great phrase and quite extensible. I will begin attempting to convince Toby that the era of on-demand walks is over. All walks are now appointment-based and I have the appointment book. How do you say that in dog?
