'Look at me, everybody! I've balanced the budget!' And indeed he had. He stood proudly in the middle of the room with the enormous 200 billion dollar budget balanced beautifully on the top of his bald head. Everyone clapped. Then suddenly the voice of astronaut Shuckworth cut in urgently on the radio loudspeaker in the President's study. 'They've linked up and gone on board!' shouted Shuckworth. 'And they've taken in the bed … I mean the bomb!'

The President sucked in his breath sharply. He also sucked in a big fly that happened to be passing at the time. He choked. Miss Tibbs thumped him on the back. He swallowed the fly and felt better. But he was very angry. He seized pencil and paper and began to draw a picture. As he drew, he kept muttering, 'I won't have flies in my office! I won't put up with them!' His advisers waited eagerly. They knew that the great man was about to give the world yet another of his brilliant inventions. The last had been the Gilligrass Left-handed Corkscrew which had been hailed by left-handers across the nation as one of the greatest blessings of the century.

'There you are!' said the President, holding up the paper. 'This is the Gilligrass Patent Fly-Trap!' They all crowded round to look.

'The fly climbs up the ladder on the left,' said the President. 'He walks along the plank. He stops. He sniffs. He smells something good. He peers over the edge and sees the sugar-lump. "Ah-ha!" he cries. "Sugar!" He is just about to climb down the string to reach it when he sees the basin of water below. "Ho-ho!" he says. "It's a trap! They want me to fall in!" So he walks on, thinking what a clever fly he is. But as you see, I have left out one of the rungs in the ladder he goes down by, so he falls and breaks his neck.'

'Tremendous, Mr President!' they all exclaimed. 'Fantastic! A stroke of genius!'

'I wish to order one hundred thousand for the Army immediately,' said the Chief of the Army.
