Sword swallowers around the world showed off what they can do on Feb. 25, 2012 during World Sword Swallower's Day. "We sword swallowers have been risking our lives to perform sword swallowing for over 4000 years," said Sword Swallowers Association International (SSAI) President Dan Meyer on the group's website. But many people either don't believe it's real, or they think the art has died out. Robin Marchant/Getty Images
