Some records, such as Olympic world records are met and surpassed as the entire world looks on. Others, although very impressive, are usually viewed as "Why would anyone even think of doing that"...Here are just a few official world records documented by the Guinness World Records, that are waiting to be broken. Charlie D'Angelo of Clifton, New Jersey, USA, has been working as an ice-cream man non-stop for 30 years since 1979 in his Iggy's Igloo ice-cream truck. Impressive or ridiculous?
