Another from Daly Waters Pub

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 chemist, "You can't treat a cough with laxatives."
"Of course you can" the assistant replied,
"Look at him........he daren't cough now!!"
