In his most dangerous and ambitious feat to date, motorcycle stuntman Robbie Knievel, the 44-year-old son of 1970s daredevil megastar Evel Knievel, has safely soared over the attention of nearly every single American between the ages of 13 and 31. 'After having shattered all of my father's records, I knew I had to do something spectacular that he would not have been able to pull off in his wildest dreams,' said Knievel, whose recent A&E reality-show stunt also landed him clean on the other side of most major nationwide demographics. 'But I never could have done it without the millions and millions of young people who either have no idea I exist or are only vaguely aware of my last name.' Experts warned that if Knievel continues to attempt demographic jumps of this size, it could end his career.
