An exhausted looking blond dragged herself in to the doctor's office. "Doctor, there are dogs all over my neighborhood. They bark all day and all night, and I can't get a wink of sleep.""I have good news for you," the doctor answered, rummaging through a drawer full of sample medications. "Here are some new sleeping pills that work like a dream. A few of these and your trouble will be over.""Great," the blond answered, "I'll try anything. Let's give it a shot."A few weeks later the blond returned, looking worse than ever. "Doc, your plan is no good. I'm more tired than before!""I don't understand how that could be", said the doctor, shaking his head. "Those are the strongest pills on the market!""That may be true," answered the blond wearily, "but I'm still up all night chasing those dogs and when I finally catch one it's hard getting him to swallow the pill!"
