"A bizarre biological discovery about punning was made by a German surgeon named Forster in 1929. Dr. Forster was operating on a patient's brain to remove a tumor. Whenever the surgeon manipulated the spot where the tumor was located, the patient would start with whatever words the doctor had just uttered and make a series of puns about his own brain surgery. He didn't mean to do it; he couldn't help it. The surgeon had discovered the spot in this patient's brain that made him pun. Since then the rare disorder of compulsive punning has been called Forster's Syndrome. It is a physical affliction a bit like epilepsy." --Kathryn Lindskoog
