This is a left over snippet from one of James's multimedia assignments. His response to many questions in life follows a similar pattern, ie. how was school today? 'Yeah it was good, but it needed more explosions.' How was your buddy's party? 'Kinda fun, but it needed more explosions.' You get the gist.
So maybe that's why he made this video? Explosions on demand! James says on his masterpiece,'this was just a blooper from a multimedia movie that i edited because I was bored. I wasn't actually dancing you fools.'
