Eccentric Teachers

I'm sure everyone has had at least one really weird teacher in their life.  In fact, if you ask me, all teachers are at least a little weird (how could they not be, after being cooped up with us kids for so long?).  But I wanted to record today for prosperity's sake- during my very serious chemistry midterm, I heard a really weird rubber-ish noise.  It's sort of the last thing you'd expect to hear while in a midterm.  So I looked  around and (without much looking, as it was bright orange) saw that my chemistry teacher was making a balloon animal.   Yes, he was not grading tests, or sleeping, or on his laptop, or doing normal teacher things, but was making some sort of four-legged creature and making a lot of noise while doing it.  Which thankfully waked me up sufficiently to finish the rest of my midterm (I was beginning to doze) but does raise some interesting questions: Where did the balloon come from?  Why did my chemistry teacher decide to make a balloon animal while we were taking the midterm?  And, Why don't other teachers make balloon animals during midterms?  It's admittedly pretty neat....
