The jonas brothers are allegedly from the year 3000. They came back from the future in their time machine (nick jonas' guitar). When Joe Jonas was singing for its a small world (The CEO of Disney enslaved them when he saw them wandering around the park without any parents), he hit a really really really high flat (but his voice squeaked) which woke up Walt Disney from his cryogenic slumber.
Walt Disney decided to hire the Jonas Brothers to work for Disney if they got total body jobs - thus attracting millions of girls to their concerts. Their song Burnin' Up has been parodied by a Youtube user named Davedays.
