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 what? s up. "He wanted something for his cough, but I couldn't find the cough syrup," the clerk explains. "So I gave him a laxative and told him to take it all at once. " "Laxatives won? t 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. He? s afraid to cough. "
