NO COPS AVAILABLE!

Late one evening, Bart heard some strange noises outside.  He peered out the back door and saw 2 or 3 guy stealing things out of his barn. 
He phoned the police and was asked, "Have they made an attempt to enter your house?"
Slightly miffed by the question, Bart replied, "No -- But they haven't emptied the barn yet."
The dispatcher said all patrols were busy, but she would send the first one that was available.
Bart waited a minute and called the police again, "I called you a minute ago because there were people in my barn. Well, you don't have to worry about them now because I've just shot all the SOB's!" Then he hung up.
Within five minutes, 3 police cars, a Swat team, and 2 ambulances showed up at Bart's and caught the burglars red-handed.
Accusingly, the officer in charge said to Bart, "I thought you told the dispatcher you shot them."
Unconcerned, Bart replied, "I thought she said there weren't any patrol available.
