I was going to bed the other night when my wife told me that I had left the light on in the shed(储藏室). She could see it from the bedroom window. As I looked for myself, I saw that there were thieves in the shed taking things. I phoned the police, but they told me that no one was in this area to help at this time, but they would send someone over as soon as they were free.

I said OK, hung up, and waited one minute, then phoned the police back, “Hello, I just called you a minute ago because there were thieves in my shed. Well, you don’t have to worry about them now because I’ve killed them all.”

Within five minutes there were six police cars in the area. Of course, they caught the thieves very quickly. One of the officers said: “I thought you said that you’d killed them!” I replied with “I thought you said there was nobody free!”
