"It's probably the most realistic way of expressing what situation I'm in - all these people trying to take things away from me, and the gorilla finding a diamond that I don't know I have and then stealing it. 'Army of Me' is so much about me actually learning that I have to defend myself. I have to stand up and fight the fucking gorilla. Once I've got the diamond and I run away with it, it becomes massive 'cos it's mine. But if the gorilla had kept it, it would have gone really tiny. That's surrealism for me."
