A lady notices that her schnauzer dog has stopped obeying her when she speaks to it, so she takes it to a vet. She tells the vet, "I think my dog is going deaf. It's as if he can't hear me."
After examining the dog, the vet returns and tells the lady, "I've got good news. Your dog isn't going deaf...It's just that schnauzers have coarse hair that sometimes builds up and plugs their ears. I cut most of the hair out, but I'm going to give you a prescription for a depilatory. It's the active ingredient in hair removal cream. Any pharmacy should have it. Swab a bit in the dog's ears for a few days and he'll be fine."
The lady takes the prescription to a pharmacist. He gives her a small bottle and says, "Now this stuff is highly concentrated....If it's for your legs, dilute it, 2 parts water to 1 part depilatory. If it's for your underarms, dilute it 5 to 1."
The lady says, "No,no, no... You don't understand: It's for my SCHNAUZER!"
The pharmacist says, "In that case, dilute it 10 to 1 and don't ride a bike for a couple of weeks."
