One Squadron-Leader who had just been promoted to Group-Captain was bursting with pride at his upgrading. He was sitting in his new office when there came a knock on the door.
"Come in!' he called, and as the door opened he picked his phone and said, "Very well, Marshal, Thank you, Marshal. Good-bye."
He put down the receiver and said to the soldier who had just entered, "Well, what is it?"
"I've just come to re-connect your phone, sir."
