My neighbour discovered that her dog could barely hear so she took it to the vets. He found that the problem was hair in its ears so he shaved both ears and the dog could hear fine.
The vet then proceeded to tell the lady that if she wanted to keep this from recurring, she should go to the chemist and buy Nair Hair Remover and rub it in the dog's ears once a month.
The lady goes to the store and gets the Nair Hair Remover. At the register the chemist's assistant tells her "if you're going to use this under your arms, don't use deodorant for a few days".
The lady says, "I'm not using it under my arms."
The chemist assistant says "Well, if you're using it on your legs don't shave for a couple of days".
The lady says "Well, I'm not using it on my legs either. If you must know, I'm using it on my schnauzer."
The assistant replied "Stay off your bicycle for a week."
