St. Baldrick's fundraiser on Thursday, September 24, 2009. St. Baldrick's is the world's largest volunteer-driven fundraising event  for childhood cancer research. Thousands of volunteers shave their heads in  solidarity of children with cancer, while requesting donations of support from  friends and family. How it all started: In 1999, Tim Kenny challenged friends, John Bender and  Enda McDonnell to find a way to give back to society. These three reinsurance  executives turned their industry's St. Patrick's Day party into a benefit for  kids with cancer. What could they do to really turn the heads - and the wallets  - of their colleagues?  John suggested shaving Enda's head since kids typically  lose their hair during cancer treatment. "People will gladly pay to see you  bald, Enda!" Never one to miss an opportunity, Enda replied, "I will if you  will," and St. Baldrick's was born.  The three planned to raise "$17,000 on the  17th," recruiting 17 colleagues to raise $1,000 each to be shorn. Instead, the  first St. Baldrick's event, held on March 17, 2000, raised over $104,000!
