A young lieutenant was passed by a private, who failed to salute.
The lieutenant called him back, and said sternly: You did not salute me. For this you will immediately salute two hundred times. At this moment the General came up.
What's all this? he exclaimed, seeing the poor private about to begin. The lieutenant explained. This ignoramus failed to salute me, and as a punishment, I am making him salute two hundred times.
Quite right, replied the General, smiling. "But do not forget, sir, that upon each occasion you are to salute in return."
