Cure the Cough!

The owner of a drug store walks in to find a guy leaning heavily against a wall.  The owner asks the clerk, “What’s with the guy over there by the wall?”

The clerk responds, “Well, he came in this morning to get something for his cough.  I couldn’t find the cough syrup, so I had him drink a bottle of laxatives.”

The owner, wide-eyed and excited shouts, “You idiot!  You can’t treat a cough with a bottle of laxatives.”

The clerk calmly responds, “Of course you can, look at him.  He’s afraid to cough.”
