A city slicker was driving in the country for the first time. He saw a creek and watched it for awhile. Then he decided to take a shortcut across it. He entered the water and immediately sank ten feet to the bottom. A farmer rescued him, and when he was back on dry ground, the farmer asked, "WHAT were you thinking?" "I don't understand it," replied the befuddled city slicker. "The water only came up to the middle of the ducks!"
