The pharmacist walks into the store to find a guy leaning heavily
against a wall. He asks the blonde clerk, "What's with that guy over there by the wall?" The blonde 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 pharmacist yells, "You idiot! You can't treat a cough with a laxative!" The blonde clerk responds, "Of course you can! Look at him, he's afraid to cough."
