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