Once Upon a time, there were these guys on horses who were riding at the same time but in different places, they've never met before and so they were riding and then there was this random guy in the street where both of them ended up playing music (he was a one-man band he played the song September), then the guys got off their horses and started dancing to the music and the horses also started to dance. Then the world blew up and the guy playing September played it as he floated in space nearby was person floating in space playing the Nintendo switch
