Camel?

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

“What in the heck is that?” asks Kate.

“A condom”, replies Pam. “This way my cigarette doesn’t get wet”.

“Where did you get it?” asks Kate.

“You can get them at any pharmacy”, replies Pam.

The next day, Kate hobbles herself into the local pharmacy and announces to the pharmacist that she wants a bulk-sized box of condoms.

The pharmacist, obviously embarrassed, taken aback, delicately asks what size, texture, brand of condom she prefers.

“Doesn’t matter, sonny. As long as it fits on a Camel”.
