I'm intimately familiar with smart asses & jack assess (having occasionally been accused of being one or the other), and running into them on more than one occasion but hadn't ever heard of a square ass. BUT, below is proof that they must exist somewhere.  I found this toilet during a recent Carlisle, KY Home Inspection. I had to take a  picture just to prove to myself that I actually saw it.  Thank goodness for digital cameras. 04/10/2010
