Back in my student days at Kent State, my roommate John had a dog named Sam. Sam was notorious for destroying baseball hats (as well as couches). My other roomy, Jason, punished Sam for destroying his hat by making him sit on a barstool wearing the hat facing away from us as we watched TV. Every now and then Sam would look over his shoulder to see if he could rejoin us. Looking back I am impressed with how smart Sam was, especially how easy it was to get him to do these things with no training involved. He also had a knack for outsmarting our other roommate Brian, but that was neither hard to do nor as impressive as sitting on a stool wearing a baseball hat.
