Two old ladies

Two old ladies were waiting for a bus and one of them was smoking a
cigarette. It started to rain, so the old lady reached into her purse
and pulled out a condom, cut off the tip and slipped it over her
cigarette and continued to smoke.

Her friend saw this and said, "Hey, now that's a good idea! What is
that your putting 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 that she could purchase them at a 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  little old lady was interested in condoms. He asked her, "what
size do you want?" The old lady thought for a moment and said, "one
that will fit a Camel."
