Earth encounters a group of time-traveling tourists on a sightseeing trip to the past who are friendly but incomprehensible even though they all do bad impressions of William Shatner and might be overpowered by a bunch of kids playing disco music on boom boxes but one cunning young man somehow convinces them that people are okay and they form a rock band and tour the galaxy, becoming interstellar celebrities.
The End.
