Talk about beef. Feltman's of Coney island, which is credited for introducing the hot dog to Coney Island in 1867, is aiming for a Guinness World Record with a 120-pound hot dog. The hope is the all-beef, five-feet long two-feet wide hot dog will be declared the world's largest. After being weighed the dog was cut into smaller portions sold for $10 each, with all proceeds going to the Headstrong Project, a non-profit that provides mental health care to combat veterans.
