A lady had a pet dog, which was one of those tiny Chihuahuas.
Sadly one day, its hair began to fall out and so she went to her local chemist and asked him if he had anything to stop hair falling out.
“Certainly, madam,” he said, as he took down a pot of ointment from a shelf.
“Rub this in for two days; but after that there must be no friction, so don’t wear a hat for a fortnight.”
“Oh,” said the lady, “it’s not for my hair, it’s for my Chihuahua.”
“In that case,” said the chemist, “don’t ride a bike for a week.”
