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 that guy over there by the wall?"

The clerk responds: "Well, he came in here this morning to get something for his cough. I couldn't find the cough syrup, so I gave him an entire bottle of laxative."

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!"
