Lady 1: "What's that?"
Lady 2: "A condom. This way my cigarette doesn't get wet."
Lady 1: "Where did you get it?"
Lady 2: "You can get them at any drug store."
The next day, Lady 1 hobbles herself into the local drug store and announces to the pharmacist that she wants a box of condoms. The guy looks at her kind of strangely (she is, after all, over 80 years of age), but politely asks what brand she prefers.
Lady 1: "It doesn't matter as long as it fits a Camel."
