2 cops are sitting in their car outside of a local bar. They were waiting to see if anyone would drive home drunk. A guy stumbles out, obviously drunk out of his mind. He falls down flat on his face. 5 bar patrons leave the bar. The cops don't care about the other patrons, they are just waiting for him to start up his car. He falls again on his face. 5 more patrons leave the bar. Finally the drunk stumbles to his car door and opens it up and sits inside. 6 patrons leave the bar. Finally the drunk starts up his car but before he could move the cops are on him sticking a breathalyzer in his face. He takes the test and passes with blood alcohol level of 0.00. The cops are pissed and asked him what the hell he was doing. The drunk replies, "I'm the designated decoy."
