The father, passing thru the son's college town late one night on a business trip, thought he would pay a surprise visit to the boy.
Arriving at the fraternity house, he knocked on the door. After several minutes of knocking, a sleepy voice drifted down from a second floor window. "Whaddya want?"
"Does Jimmy Duncan live here?" asked the father.
"Yeah!" replied the voice. "Dump him on the front porch again and we'll take care of him in the morning."
