A train was traveling to California carrying truckloads of potatoes. On the way, the train jumped the track and all the potatoes spilled out. Two potatoes met, fell in love and got married. They had a baby girl named Sweet Potato. She grew up to be 18 years old, and came home one way and said she wanted to get married. Her parents asked whom she wanted to marry. She replied "Walter Cronkite." Her parents started weeping, crying and wailing. Her mother said she could not marry him. Sweet Potato asked why not, she loved him. Her mother replied "Why would you want to marry him, he's just a commentator (common tator)."
