The Wabbit drew his contact aside to ask a private but pertinent question. "Pray tell me your name," said the Wabbit smiling a special diplomatic smile. "I am Pio Pulcinella!" said the Puppet, "how may I assist you?" "You are a political and economic puppet," whispered the Wabbit confidentially. "And I'm at your service," said Pio. "It's about my lists of priorities," said the Wabbit. Pio nodded. "Tell me more," he urged. "I keep adding to my lists and they get longer," said the Wabbit. "How are they organised?" asked Pio. "Randomly," said the Wabbit brightly. "That's not too unusual," said Pio. "so tell me which is your most important list and which is your longest?" "That's easy," said the Wabbit, "because they're one and the same list," "What's your name for that list," said Pio patiently. "Miscellaneous," said the Wabbit. Pio shook his head and thought for a while. Then he snapped his fingers. "What then" he asked," is the item at the very top of that list?" "Organising my lists," said the Wabbit. Pio Pulcinella leaned back with satisfaction and cracked his knuckles. "You have a knapsack problem," he said. "I do?" said the Wabbit. "And there is a knapsack solution," said Pio. "Do tell," said the Wabbit sceptically, since he had an overflowing knapsack at home and that was on one of his lists. "Only so much can go in your knapsack," said Pio, "so get rid of what you don't need." "I'm uncertain about what I don't need," said the Wabbit. "I have a computer programme for uncertainty," smiled Pio.
