Meet the world's oldest barber. His name is Anthony Mancinelli and he was 96 when Guinness World Records officially named him the Oldest Working Barber. That was 11 years ago! He's still at it full time. When he started cutting hair back in 1921, Warren G. Harding was in the White House and a haircut cost just 25 cents. Business is good at Anthony's barbershop in New Windsor, New York, and he's got no plans to retire.
