I'm sitting here, instead of standing in front of my Astronomy class, because this is the time for the semi-annual beauty contest known as "Student Evaluations." This is where the students rate their instructor. They are filling out forms (with number-2 pencils) while I make myself scarce for twenty minutes. Before I leave the classroom I always tell them, just to break the ice, that "now is when you get to determine how much food my kids will have to eat next year."
And when I go back, after the forms are on their way to our IT center, I'll say: "now that that's done, I can give you a pop quiz." Heh.
