Are the lyrics to the chorus of Just a reference to masturbation? Given that Radiohead fans are famously incapable of acquiring sexual partners?
You do it to yourself you do / And that's what really hurts / Is you do it to yourself just you / You and no-one else
Makes sense, doesn't it?
And is the realisation of the curse of virginity for Radiohead fans what the bloke in the video tells everyone, and why they all start lying down?
