The owner of a drug store walks in to find a guy leaning heavily against a wall. The owner asks his clerk : "What's with the guy out 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."
