A pharmacist walked into his shop

A pharmacist walked into his shop to find a man leaning against the wall.

“What’s wrong with him?” he asked his assistant.

“He came in for cough syrup, but I couldn’t find any so I gave him an entire box of laxatives”.

“You idiot” said the pharmacist “You can’t treat a cough with laxatives”.

“Of course you can” the assistant replied

“Look at him… he is too afraid to cough now!!”
