A pharmacist returns to his shop after his lunch break to see a man,pale faced,sweating and shaking,griiping the edge of the counter.

"Good Lord" he exclaims"whats the matter with this chap?" he asks his new assistant.

"He came in with a nasty cough wanting some syrup,but i couldn't find it so i gave him a bottle of laxatives instead" the disinterested youth replies.

"You gave him a whole bottle of laxatives, for a cough??????" the pharmacist is stunned. "You can't do that?"

W"Why not?" says the youth,pointing to the hapless man. "He isn't going to coough again in a hurry is he?"
