Cough Cough

Two cough sweets walk into a pub, one asks for a gin and tonic and the other for a cider.

The barman refuses to serve the red cough sweet her gin and tonic, but the green and white cough sweet is served very quickly.

"I thought we didn't serve cough sweets any more," remarked a watching bar maid.

"We don't as a rule," replied the publican, "but she looked fucking menthol."
