A very flat-chested blonde decided she needed a bra and set out to the mall to find one of her size. She entered an upscale department store and approached the saleslady in lingerie, "Do you have a size 28AAAA bra?"
The clerk haughtily replied in the negative. So, she proceeded to another department store where she was rebuffed in the same manner. She then drove to K-Mart and marching up to the sales clerk, she unbuttoned and yelled: "Do you have anything for this?"
The lady looked closely at her and replied: "Have you tried Clearasil?"
