J.D. Witherspoon, son of character actor John Witherspoon, gained over 110K YouTube subscribers on his runJDrun channel in 2017, growing to 375K+ total. A gamer, stand-up comedian, voice actor, and dog walker (according his Twitter bio), the multi-talented J.D. plays on nearly every system out there. Best known for gameplay, commentary, and reaction videos, he has also dabbled in sketches and vlogs throughout his nine-year YouTube career. His most popular video of the year, “OMG! WHEN DID I GET SO GOOD AT THIS GAME!” finds J.D. whooping his friend and fellow YouTube gamer Dashie in the 8th installment of the legendary game Mario Kart, with nearly 700K views to date. If that’s not impressive enough, how many YouTubers can claim David Letterman as their godfather?
