Through the pitch-black night, the captain sees a light dead ahead on a collision course with his ship. He sends a signal: “Change your course 10 degree east.”
The light signals back: “Change yours, 10 degrees west.”
Angry, the captain sends: “I’m a navy captain! Change your course, sir!”
“I’m a seaman, second class,” comes the reply. “Change your course, sir.”
Now the captain is furious. “I’m a battleship! I’m not changing course!”
There is one last reply. “I’m a lighthouse. Your call.”

透过黑漆漆的夜空,船长看到船的正前方有一道光. 他发了一个信号:'请变更你的航道,向东10度."

灯光回应:"请变更你的航道,向西10度."

船长很生气,又发信号:"我是海军船长!请变更你的航道,先生!"

"我是海员,二等兵,"灯光回应,"请变更你的航道,先生."

这下船长可是被激怒了."我是战船!我不变航道!"

传来最后的回答."我是灯塔.你决定吧."
