In an animated episode of HBO Backstories about Game of Thrones, co-creators David Benioff and D.B. Weiss (previously) share an amusing but seemingly painful tale describing the time Benioff challenged Jason Momoa aka Khal Drogo (previously) to a slap game. Needless to say Momoa emerged victoriously, while Benioff went to the hospital.
D.B. Weiss and David Benioff detail the time David played Jason Momoa in ‘The Slap Game.’
