It was late and Charlie was about to climb into bed when his wife informed him that there was a light on in their garden shed. Charlie started to go outside to turn off the light but noticed some people in the shed who were busy stealing his things.

He ran back inside right away and called the cops, who asked him "Are there any intruders in your house?" to which Charlie replied no and explained his circumstances. The cops told Charlie that all patrol cars were otherwise occupied, and that he should just lock his door and a uniformed cop would be at his house when one was free.

Charlie answered, "Alright," hung up, waited 30 seconds, and then called the cops again.

"Hello, I just called a short while ago because there were people stealing things from my shed. I want to let you know that they're not a problem anymore because I've just shot every one of them."

Charlie then hung up the phone. In five short minutes, three patrol cars, a SWAT team, and an ambulance arrived, and Of course, the cops caught the burglars in the act.

One of the cops snapped at Charlie: "I thought you said that you shot every one of them!"

"I thought you said there were no patrol cars free!" Charlie answered.
