Mess with old people

George, an elderly man, was going up to bed when his wife told him that he'd left the light on in the garden shed, which she could see from the bedroom window. George opened the back door to go turn off the light but saw that there were people in the shed stealing things. He phoned the police, who asked, "Is someone in your house?" and he said no. Then they said that all patrols were busy, and that he should simply lock his door and an officer would be along when available. George said, "Okay," hung up, counted to 30, and phoned the police again. "Hello. I just called you a few seconds ago because there were people in my shed. Well, you don't have to worry about them now because I've just shot all the sons of bitches!" Then he hung up. Within five minutes three police cars, an Armed Response unit, and an ambulance showed up at the George's residence. Of course, the police caught the burglars red-handed. One of the policemen said to George, "I thought you said that you'd shot them!" George said, "I thought you said there was nobody available.
