My father and the two-headed monster

My father, Thomas A. Cowan, taught law at Rutgers, the state university of New Jersey. One day while walking across campus, he saw a man carrying two cups of coffee. Being my father, he asked the man if he was a two-headed monster. He ended up walking to my father's office, where they discovered a common interest in psychology. The man was also a cartoonist, and drew my father a picture of a two-headed monster with one head saying, "No, he's a Jungian and I'm a Rankian".
