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

Her friend asks her: "What are you doing?!?"

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

So her friend asks: "What’s a condom? Where did you get it?"

So she says: "At the pharmacy"

So the next day her friend goes to the pharmacy and asks the clerk if she can get a condom. The clerk asks: "What size?"

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