An elderly man was sitting on his porch rocking back and forth. He seemed to be having a long discussion with himself. Every once in a while he broke into loud laughter. At other times, he shouted “Phooey” in disgust.

A policeman passing by stopped to watch the man and asked him what was going on. “I’m telling myself jokes,” the old man told him. “And if I say so myself, most of them are funny.”

“Then why do you keep saying ‘phooey’?" the policeman asked.

“I only say that when I heard ‘em before.”
