A pharmacist walks into his 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 liquid 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."...
