Condom Cigarette

Two old ladies were waiting for a bus, and one of them was smoking a cigarette.
It started to rain. So one of the old ladies reached into her purse, took out a condom, cut off the tip and slipped it over her cigarette and continued to smoke.
Her friend saw this and said, "Hey that's a good idea! What is it that thing you put over your cigarette?"
The other old lady said, "It's a condom."
"A condom? Where do you get those?"
The lady with the cigarette told her friend that you could purchase condoms at the pharmacy. When the two old ladies arrived downtown, the old lady with all the questions went into the pharmacy and asked the pharmacist if he sold condoms.
The pharmacist said yes, but looked a little surprised that this old woman was interested in condoms. Nevertheless, he asked her, "What size do you want?"
The old lady thought for a minute and said, "One that will fit a Camel."
