A chemist walks into his shop and sees a man leaning against the wall.
“What’s wrong with him?” he asks his assistant.
“He came in for cough syrup,” the assistant explains. “But I couldn’t find any, so I sold him some laxatives instead.”
“What?! You can’t treat a cough with laxatives!” the chemist says, horrified.
The assistant replies, “Of course you can… look at him — he’s way too scared to cough!”
