Presidents Day Origins is a video by Bobjenz. The video is also the very first appearence of Zombie George Washington. He was only intended to appear in that episode, but instead got his own series. His appearence from this episode changed very much when he made his second appearence in another Bobjenz video called I LOVE THE WALKING DEAD.
This episode might also be an origin in how Zombie Abe Lincoln became Robot Abe Lincoln
