A pharmacist comes back from his break and sees a man leaning against the wall, his face strained and nervous. He asks his assistant: "What’s wrong with that man over there?"
"He came in looking for cough medicine," she replies. "I couldn’t find any, so I gave him a whole bottle of laxatives."
"Oh great!" steamed the pharmacist. "He is going to sue us now. You don’t give laxatives to a person with a cough!"
"Well," said the clerk defensively, "look at him. He’s afraid to cough!"
