Seven Warning Signals of Cancer

I'll go with breast cancer awareness. Watching Sophia Loren makes you want to touch boobs? Good, because touching boobs is a good way to prevent breast cancer. For women, touch your boobs frequently. For men or lesbians, touch your spouse's boobs frequently. Also, remind the woman in your life to touch her boobs frequently; watch her do it, you know, to make sure she is safe from breast cancer. For bachelors, buy a "I like boobs" bracelet and try to make yourself a girlfriend at cancer awareness rallies.

Or it could just be an attention grabber. About the same time, I had a history professor who would often walk into a lecture hall full of hundreds of noisy students, pick up the microphone, and loudly say "Sex!" Without pausing, he'd continue, saying, "Now that I've got your attention, today we will learn about..." He never failed to instantly get the attention of of his students.
