An exhausted looking man dragged himself 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 man answered, "I'll try anything. Let's give it a shot."

A few weeks later the man 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 man 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!!!"
