21. Stephen King
Horror author Stephen King made a cameo appearance in the wildly popular television series Sons of Anarchy. He even rode his bike into the scene! He is an avid motorcycle enthusiast with a soft spot for the 1986 Heritage Softail he owns. He has been riding motorcycles since he was 22 years old so the cameo appearance for Sons of Anarchy made sense. Show creator Kurt Sutter got in touch with King and offered to put him on a Harley for the show. That sealed the deal; hence the scene with Stephen King aboard a bright red Harley Davidson Road Glide!
