The owner of this drug store walks in to find a guy leaning heavily against a wall.
The owner asks the new clerk: “What’s with the guy over there by the wall?”
The new 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 new clerk calmly responds: “Of course you can!, Look at him, he’s afraid to cough.”
