Here is a joke:

Two old ladies were outside their nursing home having a smoke when it started to rain.

One of the ladies pulled out a condom, cut off the end, put it over her cigarette, and continued smoking.

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 drugstore."

The next day, Lady 1 hobbles herself into the local drugstore and announces to the pharmacist that she wants a package 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: "Listen Sonny, it doesn't matter as long as it fits a camel."
