Subject: Substitute treatment
The owner of the 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 an 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!"
