A jealous husband hired a private detective to check on the movements of his wife. The husband wanted more than a written report; he wanted video of his wife's activities.
A week later, the detective returned with a video. They sat down together to watch it. Although the quality was less than professional, the man saw his wife meeting another man! He saw the two of them laughing in the park. He saw them enjoying themselves at an outdoor cafe. He saw them dancing in a dimly lit nightclub. He saw the man and his wife participate in a dozen activities with utter glee.

"I just can't believe this," the distraught husband said.

The detective said, "What's not to believe? It's right up there on the screen!"

The husband replied, "I can't believe that my wife could be so much fun!"
