Happy "Happy Day!" Know what I mean?

So my kindergartner is approaching the end of his first year of school.  They have to know some basic information to make it out alive: the ABC's, count from 1-100, their address and phone number, etc.  One of their tested items is to recite, in order, the days of the week.

So, the wife, being the competitive scholarly type is diligently working with him in the dining room.  I, of course, am under no stress because I realize that this common knowledge is innate to the culture and Michael will pick it up eventually anyway.  I am positive that my son will not be calendarally-challenged for life.  World's ending this year on 12/21 anyway.

In the dining room, Jessica joined in to help with the tutoring.  Sunday, Monday, Tuesday, Wednesday, (I wish this thing worked like excel - then I could just drag a handle across the page and autofill all the days of the week) Thursday, Friday, Saturday (is that right?).  Over and over again.  Which probably meant Michelle had them all memorized.  My 3-year old is as smart as they come; and a world class manipulator.  

Back to the study session.  Michael was getting pretty good at reciting the days.  Soon he was going all by himself.  Then, ever the quizzical introspective child that he is, looked at his tutors and exclaimed, "Saturday?  Saturday?  Why do they call it Saturday?  There is no school on that day.  They should call it Happy Day!"

Followed, of course, by Fun Day.  Except, you still have to go to church on that day.
