An old lady brings her dog to the vet as it seems to be having problems with its hearing.
The vet cleans the dog's ears and advises her to use hair removal cream on the dog's ears once a month as a means to reduce build-up and avoid the problem.
The old lady leaves the vet and heads straight to the pharmacist to buy hair removal cream.
The pharmacist says "If you're using it on your legs, wear a dress for a couple of days to avoid any irritation. If you're using it in your arm pits, wear a singlet for a couple of days to avoid any irritation. By the way, where do you intend using the cream?"
"On my schnauser," says the old lady.
The pharmacist replies "In that case, I'd avoid riding a bike for the next week."
