Despite differences between them due to comments Dynamite Kid made about Stu Hart in his autobiography, Bret still regards him as "pound-for-pound, the greatest wrestler who ever lived." Dynamite Kid began taking steroids in 1979, when Big Daddy Ritter, aka the Junkyard Dog, introduced Billington to the anabolic steroid Dianabol.
