He bought a DVD player. He went home. He unplugged the old DVD player from the living room flat-screen TV. He hooked up the new player. He plugged the old player into the 10-year-old TV in the bedroom. His wife came home. She said, "Why didn't you just plug the new player into our bedroom TV? You always do everything the hard way." He said, "Because I couldn't. New DVD players don't use those cables with the red, white, and yellow pin connectors. They use cables with HDMI connectors, which are rectangular. I can't plug a rectangular connector into a round hole." She said, "I don't believe that." He said, "You don't believe that? What you don't believe doesn't change the facts. Some people don't believe the Earth is round." She said, "Well, I'm not one of those people. I just don't believe that you know what you are doing."
