Hurry up!

One evening, a woman hears sounds coming from her garden. She looks out of the window and sees three men breaking into her garage. She calls the police, but they tell her it could take a while, because they don’t have anyone in her area. The woman puts the phone down, counts to 30 and then calls again. “I just rang about some burglars,” she says. “Well, you don’t have to worry now. I’ve shot them all.” Within five minutes, there are six police cars outside her house, and the burglars are caught. One of the officers approaches the woman. “I thought you said you’d shot them.” The woman replies, “And I thought you said there was no one in my area.”
