The three videos below tell the story better than we ever could, but the basic arc runs thus: John Chu, the director behind dance flick Step Up 2, challenged Miley Cyrus and her pal Mandy to a dance battle via his YouTube blog; Miley and Mandy responded with a video of their own; then Chu and dance maniac Adam Sevani made a response-to-the-response video, featuring cameos by Lindsay Lohan (?) and Adam Sandler (??). Now the three videos have 5.3 million views between them.
