My wife found out that our dog (a Schnauzer) could hardly hear, so
she took it to the veterinarian. The vet found that the problem was
hair in the dog's ears. He cleaned both ears, and the dog could then
hear fine. The vet then proceeded to tell Andrea that, if she wanted
to keep this from recurring, she should go to the store and get some
"Nair" hair remover and rub it in the dog's ears once a month.

 Andrea went to the store and bought some "Nair" hair remover. 
At the register, the pharmacist told her, "If you're going to use
this under your arms, don't use deodorant for a few days."
Andrea said, "I'm not using it under my arms."

The pharmacist said, "If you're using it on your legs, don't use body lotion for a couple of days."
Andrea replied, "I'm not using it on my legs either. If you must
know, I'm using it on my Schnauzer."

The pharmacist said, "Well, stay off your bicycle for about a week."
