Cough syrup

[dakao]

The owner of this 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 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."
