Two old ladies standing at a bus stop. The first old lady lights up a Silk-Cut cigarette. A few minutes later it starts to rain .

The lady reaches into her handbag and pulls out a condom. She puts it around the cigarette.

The secound old lady asks "Why did you put a condom around your cigarette?"

The first old lady replies "It keeps my Silk-Cut dry"

The next day the secound old lady lights up a cigarette. She remembers the first old lady with the condom and thinks it's a good idea as it starts to rain.

She goes into a chemist and asks for some condoms.  The man behind the counter asks what type she would like. The old lady replies: "It doesn't matter, as long as it fits my Camel."
