Time traveler injured in hoverboard fire

(Earth) An injured time traveler is blaming faulty manufacturing for the fire and burns sustained after his hoverboard caught fire unexpectedly. When the man was asked by his startling resemblence to famed time traveler ancestor Martin McFly, he noted that his family genetics have made every single man in their family look the same for thousands of years, with the single exception of one. For years rumors have dogged the McFly family of taboo relationships that may have caused a rift in the spacetime cotinuum.
