"Drugstore Dummy" joke
Craig, the clerk in the small drug store, wasn't much of a salesman. He could never find the item the customer wanted. Joe, the owner, had had enough of his clerk's incompetence and warned Craig that the next sale he missed would be his last.
Just then a man came in, coughing, and asked Craig to find a remedy. Try as he might, Craig simply couldn't find the cough syrup. Remembering Joe's warning, he sold the man a box of laxatives and told him to take it all at once. The customer did as Craig said and left. Joe witnessed the whole transaction and confronted Craig.
"A laxative won't cure a cough, you fool!" Joe shouted.
"Sure it will," Craig said. "Give that guy a few minutes for the stuff to kick in and he'll be afraid to cough."
