Berta and Ethel are two older ladies who were outside smoking cigarettes when it starts rain. Berta reaches into her purse and pulls out a condom with the tip cut off. She slides the condom over the cigarette and resumes smoking. "What are you doing?" asks Ethel. "Oh, this?" replies Berta, "I always carry a condom to put on my cigarettes when it starts to rain." Thinking this is a terrific idea, the next day Ethel goes to her pharmacy to buy condoms. Realizing that she'd never done this before, she asks a clerk for some help. "Of course, ma'am," says the clerk, "what size do you need?" Ethel replies, "Oh I don't know, but it needs to fit a camel."
