Sleeping Pill

An exhausted looking blonde dragged herself into the doctor’s office. “Doctor, there are dogs all over my neighborhood. They bark all day and night, and I can’t get a wink of sleep.”
“I have good news for you,” the doctor answered, rummaging trough 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.”
A few weeks later the blonde returns, looking worse than ever and she seems to have lost a lot of weight. “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 blonde 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.”
