A woman was worried her elderly little dog was going deaf. So she took it to the vet. "Don't worry, Mrs Smith, it's just a build up of matted hair in its ears. I can give you a prescription, or just simply go to the pharmacist and ask for 'Hairaway'. That's a cheaper option." The woman thanks the vet and goes to the pharmacy. She takes the Hairaway to the counter. The pharmacist says "This is strong stuff. If it's for your armpits, don't use deodorant for two days." "No, it's not for that." "I see. Then if it's for your legs, don't wear trousers for a week." "No, it's not for that. It's for my Schnauzer." "In that case, don't ride your bicycle for a month."
