A jealous husband hired a private detective to check on his wife's movements, insisting on video evidence rather than just a written report.
A week later, the detective returned with a video. As they watched the less-than-professional footage, the husband saw his wife meeting another man. He watched them laugh in the park, enjoy an outdoor cafe, dance in a dimly lit nightclub, and participate in a dozen other activities with utter glee.
"I just can't believe this," the distraught husband said.
The detective replied, "What's not to believe? It's right up there on the screen!"
To which the husband answered, "I can't believe that my wife could be so much fun!"
