A customer walks into a pharmacy and asks assistant for an
anal deodorant. The assistant explains that they don't stock
them. The man insists that he bought his last one from this
store. The assistant passes man on to the pharmacist, who
explains that store has never stocked such an item. The man
explains he bought his last one from this store only weeks ago
and has done for several years. The pharmacist asks man to
bring in his last purchase and he will try to match the product.
The following day, the man returns to the pharmacy and shows
the deodorant to the pharmacist. The pharmacist asks why the
customer thinks this is an anal deodorant, when it is obviously
of the underarm stick variety.
The customer explains that instructions on reverse state, "Push
up bottom to use."
