A blonde, who could not get proper sleep for weeks, went 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."
Doctor was happy as he wanted to test new medicines on sleeping disorder and she seemed as the right person for that.
He said, "I have good news for you", showing 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."
"Amazing," the blond answered, "I'll try anything. Let's give it a shot."
A few days passed. The doctor was happy that his medication was working well on the blonde.
After a week, the blond returned, looking worse than ever. "Doc, your plan is no good. I'm more tired than before!"
The puzzled doctor said, "I don't understand how that could be", shaking his head, "Those are the strongest pills on the market!"
The blonde replied, "That may be true. 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!"
