My business mentor, Charles Fisher, was a prankster aficionado. He did things like poke a tiny pin hole in the side of your soda can, just below the tab opening, so that every time you took a sip it would dribble down your chin. For all new employees, he would leave pink return call slip on their desk with the phone number to a funeral home asking them to return a call to “Myra Maines.” He always had a joke ready for any occasion.
