The pharmacist walks into the store to find a guy leaning heavily against a wall.
He asks the counter 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 a bottle of laxative.”
The pharmacist said:”You can’t treat a cough with a laxative!”
The clerk responds, “Of course you can! Look at him, he’s afraid to cough!”
