A woman's dog develops a rash that makes its skin very sensitive and requires the application of an ointment to make the problem go away, so the veterinarian sends the woman to a pharmacy with instructions to buy a hair-removal solution.
As the pharmacist rings up the purchase, he cautions the woman: "This might cause some irritation, so I recommend avoiding pantyhose for 24 hours."
"Oh, it's not for my legs," she replies.
"In that case," the pharmacist tells her, "I would stay away from wool sweaters for three or four days, because your underarms might be a tad uncomfortable."
"I won't be using it on my underarms," she says, growing impatient.
The pharmacist pauses, looking a bit confused.
"Look," she says, "if you really must know, I'm buying this for my schnauzer."
"Aaaah," the pharmacist says with a look of understanding. "In that case, you shouldn't ride a bicycle for at least a week!"
