Howard dragged himself into his doctor's office looking very exhausted.
"Doctor Kaine," he said, "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, Howard," Doctor Kaine said, 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," said Howard, "I'll try anything. Let's give it a shot."
Dr. Kaine gave him the pills. Howard thanked him and left.
Two weeks later, Howard came back to Dr. Kaine's office looking worse than ever.
"Doc, your plan is no good. I'm more tired than before!" Howard exclaimed.
"I don't understand how that could be," said Dr. Kaine, shaking his head. "Those are the strongest pills on the market!"
"That may be true," answered Howard wearily, "but I'm still up all night chasing those dogs and when I finally catch one it's hard to make them swallow the pills."
