A poster for the "Save 2nd Base" fundraiser at Tao restaurant in Las Vegas last month, for example, depicted a curvy model in a string bikini, noting "everyone in pink bathing suits receives open bar." An online version of the ad went viral, spread by outraged cancer survivors. The Las Vegas restaurant did not return phone calls for this story.

Although proceeds were to benefit Komen, the cancer group's spokeswoman Andrea Rader says Komen hasn't heard how much was raised, and won't accept the donation. Rader says the Las Vegas restaurant was supposed to get Komen's approval before launching the ads, but did not. "We would never have approved that."
