King Friday

In the neighborhood of Make Believe segments, anytime that King Friday was already in the castle or coming out and if anybody human or one of the puppet characters were already there, or approached he would say their name and also "I presume", and that person or puppet would say correct as usual King Friday", or "Uncle Friday" if it was Lady Oberlin. Bit how come nobody ever said even as a joke, just to see how he would react, "incorrect as usual King/Uncle Friday", even of course that he would have also seen that person.
