It's 1887 and they got this movie guy and he says he wants to make a horse movie and he takes about 100 photos of a horse moving around and he says, "man, I want to look at these photos really quick how quick can I look at them?" And so he looks at the photos super quick. People started to freak out when they saw it because it was the first time anyone had ever seen a horse movie before.
