Curing a Cough

The owner of a drugstore arrives at work to find a man leaning heavily against a wall. The owner goes inside and asks his clerk whatís up. "He wanted something for his cough, but I couldnít find the cough syrup," the clerk explains. "So I gave him a laxative and told him to take it all at once." "Laxatives wonít cure a cough, you idiot," the owner shouts angrily. "Sure it will," the clerk says, pointing at the man leaning on the wall. "Look at him. Heís afraid to cough."
