The woman went to the pharmacy and chose a dilapatory and brought it to the counter.
The pharmacist started going over the warnings:
If you use this on your legs, do not wean long pants for at least 48 hours. If you use this under your arms . . .

It’s for my Schnauzer . . .
The pharmacist replies:
Oh! Well, then make sure that you don’t ride a bicycle for at least 48 hours

Never ride a bike after putting a dilapatory on your schnauzer
