A young woman had entered her dog in the dog show in the smooth-haired breed category. To give it an advantage, she went to the chemist for some hair remover.

The chemist gave her the product requested and advised, "Just remember to keep your arms up for at least five minutes."

"Errr... it's not for my armpits," she flustered, embarrassed, "it's for my Chihuahua."

"Oh well, in that case," said the chemist, "don't ride a bike for twenty minutes."
