Two old ladies are standing at a bus station and one of them is smoking. Suddenly, it starts raining, so the one who is smoking takes out a condom from her purse, cuts the edge off and puts it over the cigarette.

 

"What are you doing?" her friend asks.

 

"I don't want my cigarette to get wet so I covered it with a condom," she replies.

 

"Where did you get it?" her friend asks.

 

"At the pharmacy," she replies.

 

So the next day her friend goes to the pharmacy and asks the clerk if she can get a condom.

 

"What size?" the clerk asks.

 

"I dunno," she replies, "one that will fit a camel."
