Jane  and Arlene are outside their nursing home, having a drink and a smoke, when it starts to rain. Jane pulls out a condom, cuts off the end, puts it over her cigarette, and continues smoking.

Arlene: What in the hell is that? 

Jane : A condom.   This way my cigarette doesn't get wet.

Arlene: Where did you get it? 

Jane : You can get them at any drugstore.

The next day, Arlene hobbles herself into the local drugstore and announces to the pharmacist that  she wants a box of condoms. 

The pharmacist, obviously embarrassed, looks at her kind of strangely (she is after all, over 80 years of age), but very delicately asks what brand of condom she prefers.
