A tired-looking blonde woman shuffled into her doctor’s office, dark circles under her eyes. “Doctor,” she groaned, “the neighborhood dogs bark constantly – day and night. I haven’t slept properly in weeks!”
The doctor smiled knowingly and pulled out a sample packet. “These new sleeping pills work wonders,” he assured her. “Take a few and your problems will disappear.”
“Thank goodness,” the blonde sighed. “I’m desperate enough to try anything.”

Two weeks later, she returned looking even more exhausted. “Your pills made everything worse!” she complained. “Now I’m more tired than before!”
The doctor was baffled. “That’s impossible – these are the strongest sleeping aids available!”
“Well,” the blonde explained wearily, “I’m still up all night chasing those dogs around, and when I finally catch one, it’s nearly impossible to make them swallow the pills!”
