"The owner of a drug store walks in to find a guy leaning heavily against a wall. The owner asks the clerk, ""What's with that guy over there by the wall?"" The clerk says, ""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 owner says, ""You idiot! You can't treat a cough with laxatives!"" The clerk says, ""Oh yeah? Look at him, he's afraid to cough!"" "
