Cough Syrup:
The owner of this 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 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 a entire bottle of laxative."
The owner, wide-eyed and excited shouts: "You idiot!
You can't treat a cough with a bottle of laxatives!"
The clerk calmly responds: "Of course you can! Look at him;
he's afraid to cough!"
