Started by Lance Armstrong, it has now become fashionable for various causes to raise money by selling bracelets that help make a cause more visible. A bracelet for breast cancer awareness reads, "I (heart) Boobies -- Keep A Breast."
Nick Morgan, a high school student who lost a family member to breast cancer, had the audacity to wear his bracelet to school. He was given detention, and the school has now banned the "offensive" bracelet from campus.
The offended teacher who first assigned the detention, by the way, is a science teacher. You just know she's the one they trust to teach sex ed.
